Avoid length limit for input fasta ids

[alpae]

The enforced length limit on the fasta IDs is annoying.

FastOMA/FastOMA/check_input.py

Line 50 in 38b2991

if len(prot_rec_id)>60: # todo 85 is the limit without considering ||s.

we could replace all the IDs with a lookup table. however, there are a few things to consider:

• doing it before OMAmer mapping means the results cannot easily be reused / existing omamer placements are invalid.
• debugging will involve an extra (mental) mapping step.
• generally requires all reporting steps to replace the mapping again.

One option could be to store the mapping in a sqlite database. comments wellcome.

actually, if the problem is only coming from FastTree, we could also extend the FastTree-Wrapper to include a label transformation on the fly. or are there other places with limits? Mafft?
