if I try to send - say "OK", no actions on contioner.

saw this GH issues post about IRremoteESP8266 and wondered how an LLM would get on with updating the OpenBeken integration from v2.8.4 to v2.9.0:
https://github.com/openshwprojects/OpenBK7231T_App/issues/2014

The process brought up a couple things that may or may not be anything. I am curious about them

itoa.cpp
is this local itoa/ltoa/utoa/ultoa replacement correct?. it looks like it resets the output index inside the loop, which would seem to make multi-digit numbers collapse down to a single digit

digitalWriteFast.cpp
In the non-Beken path, INPUT_PULLUP appears to call the pulldown helper, and INPUT_PULLDOWN appears to call the pullup helper. On the Beken side it’s mapped the expected way around. was there a platform-specific reason for that?
