include non-human transcripts to pvacsplice

[mhoang22]

previously combine_input.py searched for transcript_id starts with 'ENST' in the annotated_vcf(tsv). this would exclude non-human transcripts.
we change the code so that it searches for transcript_id contains ENS*T instead, to include non-human transcripts.

Notes on ensembl transcript name:

(example: mice: ENSMUST, dog: ENSCAFT, cat: ENSFCAT)

+1 this looks good but I wonder if we should add some non-human tests here to cover this specific case. In tests/test_pvacsplice_combine_outputs.py you can basically replicate/copy the test_combine_inputs_runs_and_produces_expected_output test and use your dog test files if we're ok with putting them publicly on GitHub. You'll need to use intermediate files produced by pVACsplice for the junctions and variant file inputs.
