Contribution description
Hello 🦭
this adds the crc16-fcs/ibm sdlc to RIOT.
Because this is afaik the first crc in riot with an xout value, I had to slightly tweak the crcs API to provide start and finish functions.
Testing procedure
I provide a unittest:
make -C tests/unittests/ tests-checksum termIssues/PRs references
Needed for #21418
