Old ignore system used SubGhzProtocolFlag_* This enum was saturated, and started taking more bytes than on OFW This caused BusFault when using apps compiled for OFW, like from catalog Crash is because of incompatible memory structure New ignore system uses own enum at end of struct This is binary compatible with OFW and correct solution for future
