Fixed an issue which caused invalid mutations if a deletion starts in a promoter of a gene, and passes the gene end.

Bug fixes.

Ensures that `GeneDifference.amino_acid_sequence` is the same length as other difference arrays. This was changed with the introduction of including nucleotide SNPs in cases of synonymous AA SNPs. Now in cases of this, the `amino_acid_sequence` is correctly padding with `None` values in positions that these nucleotide SNPs are introduced.

Added fix for github actions to ensure only a single action is triggered by a release

Fix depreciation warning caused by changes in v1.0.12

Addition of nucleotide mutations for cases in which there are synonymous mutations.
This allows for more specificity when referring to synonymous mutations - useful in cases such as fabG1L203L which has R for 1 nucleotide change, but U for another. With both being possible within the synonymous mutation, the nucleotides should be inspectable too

Additional big fixes relating to deletions which cross gene borders

Bug fix. Deletions which start within a gene and pass the gene end are now accepted as valid variants
