just need somewhere to put this down.

for protocols with weird multibit / bit combination flags: ie, protocols/growatt/growatt_bms_canbus_v1.04.registry_map.csv

can maybe implement a multibit flag solution such as.
"b1&b3" : "status"
"b1&b4&b7" : "different status"

alternatively, it could probably be hacked in by splitting the bits into uints... but it might not be the cleanest solution as the flags' would get their own variables.
