ON this version is possible to have the width of the modulator associated
to the RF pulse (to be used on MEBT systems)

ICSHWI-9069

Removed almost all use of dbpf.
Remove island_* snippets (now all IOCs should use evrisland-base.iocsh)

This way is possible the set the frequency as a frequency value
(and not a selector). The read back value should be used as a referency
of the current set frequency.

These changes allow to use Mixed Mode synced with a 14Hz Pulse

New frequency events

See merge request e3/wrappers/rf/e3-evrisland!10

Include possibility to change between modes

See merge request e3/wrappers/rf/e3-evrisland!9

And include default delay for beam start/beam end for global mode

Set pulsers to react to event 15; Removed the pre-pulse delay when global mode is on; Set pulser 0 (modulator) to trigger upon arrival of RFSt event;

It is missing to define how to manage Beam Start an Beam End

So the island event is used for the timestamp as default

This way the EvtA will always have the right timestamp, and can be
used by any other IOC.
