make usart write buffer const sub out magic numbers with defines fix edge case handling 255/256 byte frames (including crc) add sanity checks to avoid buffer overrun on some "should never happen" edge cases don't wait for rats reply from card before listening to next reader frame cap fsci to 8 (256 bytes) as that's the most the proxmark3 codebase currently handles eliminate 1k of ram usage by tweaking how emulation responses are sent
