Mostly just change names of files or classes.

If check is not made, ioc will try to write to register in the beginning and fail, crashing the application.

It wasn't supposed to be here. Should be named configFE only.

VmmTbl now inherits from asynPortDriver instead of FrontEndBase.
It has VmmTblAPI as a class component.

Thus, everything that used pRMM->foo(); such as pRMM->setStringParam(addr_list, vmmHybFwVersion_[hyb], pVMMConfig.readFwVersion(hyb).c_str());
are simply foor(); (equivalent to this->foo();)

Everything that used pVMMConfig.foo(); now uses pVmmTblAPI->foo();

configFEN had its name changed to configFE since the last configFE did
nothing.
Old configFE was removed.

In the end, findRegister() was not moved to VmmTblAPI because it seems
to be searching for a given register name based on an epics parameter.

vmm_config is now called VmmTblAPI. Following [Loki's example](https://gitlab.esss.lu.se/nice/dev-epics-modules/fe-r5560-loki/-/blob/include-api-on-module/r5560LokiApp/src/r5560LokiApi.h?ref_type=heads)
it inherits from RMM API's FrontEndBase, which means it doesn't need
pFEN as a class parameter anymore.

This breaks the whole application compilation, but it was already broken
in the new API structure.

It you compile only with

SOURCES += $(APPSRC)/VmmTblAPI.cpp

in the Makefile, it works. My intention is to keep adding the other
files now.

Other APIS follow the same structure. No need for a cpp file for this.

Substitution file is used in module build to set channel names, since that shouldn't change
too much with time and particular detector.

VMM and Hybrid numbers are left to be changed in the st.cmd file since that can change more often.

Now, for VMM, the pattern is:
$(R)$(H)$(V)$(C)$(CH)

R: Usually "NDet-VMMHYB-00". No colon after.
H: Hybrid number in range 0-5
V: VMM chip number in range 0-1
C: Colon Between device name and property Should be ":" but is a macro in case anyone
   decides that shouldn't be there anymore.
CH: Channel/register being set. Can be ST, SL, SC, STH, SM or SMX

Also, to make naming more visible and dynamic, stop using substitutions file.

Same as previous commits.
Basically add a list of EPICS parameters for each SMX channel and register, for each Hybrid-VMMChip pair.
List is indexed by Hybrid and VMM number.

Records are created with .sub file to avoid useless code repetition.

Nothing new, same stuff as the last previous commits.

This commit makes it possible to change all 64 SL registers for a given Hybrid-VMM pair.

The map keys are going to be used as register names
in the setRegister function, so they should be lowercase.

If for some reason findRegister cannot find what VMM and Hybrid should it operate into,
error message should help the poor soul who is operating IOC at the time.

This commit organizes all possible register parameter lists in a map.

This is so findRegister can search each register map from a single data structure
instead of having to hardcode every new register parameter list in the findRegister function.

Now, to add a new register, developer should only need to:

  1 - Create the register parameter list and add it to the map in vmm_tbl.h:39-41
  2 - ... I think that's it(?)

Also, asynPrint should tell which hybrid, vmm and register are being affected by the operation now.

ST register is not hardcoded into template file anymore.
This will make it easier to add new registers, I hope.

Before this, Any caput to AllST-S record would only set channels values to
hybrid 0, vmm 0 because of hardcoded values.

This commit makes the vmmST_ an array with epics parameters.
The function getPair discovers the HYBRID-VMM pair for the parameter
that was called and sets the correct pair register's values.

Also, records are loaded with .sub files so we don't need to keep repeating
record names with different numbers.

All have been tested and works.

Nothing should change with this.

Before this, you would need to put array of values into ST-S.
Now you can simply put 1 or 0 into AllST-S and it will set all channels.

OOPT "on change" field is needed because for some reason without it even
if you put PINI=NO in all these three ST-S records, it processes on IOC
initialization, which I don't think is desired.

Add array of 64 elements. When you put into it, the nth element will
set the nth ST channel of VMM to the value put to it.

Added writeInt8Array method.
Added the ST-T aao record.
Added vmmST parameter to VMM class.
Removed TO-DO comment that was about adding this functionality.

In this moment we are using only hybrid 0, this must be changed in the future
