also added the related .map files which tell mapping of assembly instructions
and functions into the code space. these files can be used to locate the hex
addresses contained in the diagnostics

- built:
  - mc4plus v3.40, build 02 nov 2021 @ 12:11
- main changes from previous release are:
  - the fatal error handler which forces the the restart sends even more advanced diagnostics able to trace
    further actions inside the RTOS (see robotology/icub-firmware#213).
    these diagnostics are to be decoded w/ relevant .map file.
