arduino as a library will not build with -flto. I can't figure it out. so we
waste some space compared to what platformio was building. oh well. there's
still over 1K of space left for programs.
was able to put the button on PA2 and confirm PA1 for the LED data. because we're using PA2 for the button, we have async sleep support and no longer need to do all the button checks and mitigations for the partial-async pin which was used before.
compiled code size is slightly larger after removal of mitigations and other minor fixes...
