Point out limit in AVR #1

Closed elvis-epx closed 5 years ago

It seems that there is a limit of 128 bytes in message + redundancy when using this library on AVR (in my case, LoRa32u4). It would be nice to point out in documentation that library does work on AVR with limitations.

Nevermind, the problem seems to be sheer memory. 100+25 code seems to use up all memory available to AVR. Same happens if a number of RS decoders are instantiated and used. Seems to work ok with 40+10, up to 60+15. In ESP32, one can use 200+50 without issue.
