Memory sizing and checking on non-AVR platforms is off by 4x #374
Description
When using 32 bit platforms (RP Pico, ESP32) the memory checks in allocateMeme.cpp look at "elements" rather than "bytes". This works for the AVR platforms where we are using 8bit elements, but for 32bit platforms this results in 4 bytes being allocated with only 1 byte being available for use.
Could be fixed by passing the byte size, using compiler flags, or possibly by checking std::size_t .
Repro steps: Make a large community device. Note that the value for -DMEMLEN_CONFIG must be 4x the size required by the class.
