arduino : fix bug in the Reed-Solomon code that causes crashes on some MCUs
...
The issue was first reported here:
https://github.com/ggerganov/ggwave-arduino/issues/1
We were incorrectly reading the "log" array in RS::gf::pow() function.
It is surprising how this code even worked on the other microcontrollers.
Probably we have been reading bogus values, so I expect the performance of
the transmissions to improve after this change.

the output buffer and thus limits the size of the Rx payload that can be
decoded and stored.
