feat: Reduce risk of corrupt radio.yml (#1481)

* reduce risk of corrupt radio.yml #1412

Adds CRC16 checksum to radio.yml when saved.
Adds save to temporary file, folowed by rename to radio.yml
Adds check on load, with fall-back to temporary file

* Made sure that only the first read block of radio.yml is checked for the 'checksum' value.
Added checksum generation on radio.yml produced by conversion.

* Added namespace.
Github actions triggered build failed on this - compiler difference.

* Fixed typo in code not run locally.

* Made checksum result code a enum class.
Fixed null-poionter dereference bug.

* Added check and handling for radio.yml file not read (will be handled as if checksum failed)
Added evaluation of checksum when radio_new.yml is read.
Added f_unlink() calls before f_rename() to ensure the target filename does not exist.

* Added radio.yml cheksum handling to Simulator/Companion.
Cleaned radio firmware handling of checksum field up to be newline agnostic.

* Added handling of files without checksum.
- Letting files pass the check if no checksum field is present (old files) and the size is realistic (25 bytes)

* Fixed bug causing new conversion from binary if no radio.yml BUT a radio_new.yaml
is present in the filesystem.

Now the conversion is only performed if neither file exsits.

* repair rebase problems

* rerun yaml generator

* fix another rebase problem

* update text in companion to be more meaningful when the radio.yml file has a checksum error
fix wrong error message in trace

* add trigger to check radio config when leavin menu_radio

* fix: add handling for temporary and error yaml radio settings files to simu/simulator/libsimulator

* fix corner cases when comverting non crc-ed files

* chore: Tweak radio data warnings for screen sizes
- Changed the define to be a little shorter
- Added missing define for TW
- Three string lengths to suit 128, 212 and basically colorlcd
