pVAC-Seq v4.0.3

We added an optional downstream analysis tool to generate an annotated fasta file from a VCF with protein sequences of mutations and matching wildtypes. This tool can be run with the pvacseq generate_protein_fasta command.

This release fixes a couple of errors that were introduced in the previous version which would occur during the processing of certain inframe indels.

This version also fixes an error that would occur if the number of variants to process was a multiple of the chosen --fasta-size.
