fix(docs): Update get_genomic_tx_data function

[jarbesfeld]

closes #443

I investigated this function further and it seems the issue may have been that more clarification was needed for this part of the function docstrings:

:param pos: (start pos, end pos).

Since UTA uses inter-residue coordinates, I interpreted this as describing the inter-residue coordinates for a part of sequence that is being examined. I updated the docstrings to describe this, and modified the tests so that both positive and negative transcripts are being examined.

@korikuzma It looks like coordinates are converted to inter-residue before running this method, as seen in this example from the alignment.py module.

The other place where this method is run is in the mane_transcript.py module. It is called in _get_and_validate_genomic_tx_data function.

It looks like the position coordinates are converted to inter-residue coordinate by using the get_inter_residue_pos function from the utils.py module.

Should update the docstring to reflect this

@korikuzma When I re-ran the tests I saw some were failing because some of the Ensembl gene versions were out of date. It looks like there may have been a update over the weekend, so I incremented the gene accession versions and now the tests pass

Think we might want to scope the fix in the PR title: fix(docs)
