/*
To enable log only for one (or more) group, you can use this formula:
log_level = NFC_LOG_PRIORITY(main) + NFC_LOG_PRIORITY(group) * 2 ^ (NFC_LOG_GROUP(group) * 2)
Examples:
* Main log level is NONE and only communication group log is set to DEBUG verbosity (for rx/tx trace):
LIBNFC_LOG_LEVEL=3072 // 0+3072
* Main log level is ERROR and driver layer log is set to DEBUG level:
LIBNFC_LOG_LEVEL=769 // 1+768
* Main log level is ERROR, driver layer is set to INFO and communication is set to DEBUG:
LIBNFC_LOG_LEVEL=3585 // 1+512+3072
*log_priority_to_str(const int priority);
