RAM constraints on Pico W were causing a hardlock. This change allocates the results struct, config and motion config on gc_heap to relieve system RAM pressure.
Fixes#448
MicroPython has changed MP_REGISTER_MODULE to use only *two* args and now runs the preprocessing stage on files before running makemoduledefs.py.
This change avoids the build exploding, since the new regex matches the last two args as a single argument and generates a malformed module defs include.
The pattern here exploits the fact that 1.18 and below do not preprocess files, so *both* MP_REGISTER_MODULE lines are included in the source, but *only* the three arg version is matched by regex.
In >1.18 the files will be processed and the three arg version removed before makemoduledefs.py processes it.
