Rename readhistory2
The function ifcfastint_read_history
(https://gitlab.esss.lu.se/rflps/fim/fimioc/-/blob/master/vendor/ifcdaqdrv/ifcfastintdrv.c?ref_type=heads#L253) is not being used and should be removed in favor of ifcfastint_read_history2
(https://gitlab.esss.lu.se/rflps/fim/fimioc/-/blob/master/vendor/ifcdaqdrv/ifcfastintdrv.c?ref_type=heads#L2586).
Also, remove the "2" suffix from it.
The only place that this function is used is in https://gitlab.esss.lu.se/rflps/fim/fimioc/-/blob/master/fimiocApp/src/IFCFastIntInterlockFSM.cpp?ref_type=heads#L1186 and https://gitlab.esss.lu.se/rflps/fim/fimioc/-/blob/master/fimiocApp/src/IFCFastIntInterlockFSM.cpp?ref_type=heads#L1724
