Rethink IMAP Lo coincidence type bitwise flagging #2621
Description
Currently it is a string for the coincidence_type variable in Lo L1B. With each bit of the string being a bit flag. The order of it is in (tof0, tof1, tof2, tof3, cksum, mode).
It would be better to have bitflags class that can be bitwise combined and evaluated to know exactly which bits mean what.
CoincidenceType(IntFlag):
TOF0 = auto()
TOF1 = auto()
TOF2 = auto()
TOF3 = auto()
CKSUM = auto()
MODE = auto()
# check TOF0
x & CoincidenceType.TOF0
# golden triple
GOLDEN_TRIPLE = CoincidenceType.TOF0 & CoincidenceType.TOF1 & CoincidenceType.TOF2 & CoincidenceType.TOF3 & CoincidenceType.CKSUM & CoincidenceType.MODE
