Major changes major update of add_peptide() function. annotate if junction leads to frame_shift revised format of resulting peptide sequence: frame_shift: WT flanking size + until next stop codon non frame_shifts: WT flanking size + novel sequence/breakpoint + WT flanking size/until next stop codon Minor changes minor bug fix in exon_in_intron() function update to Roxygen-7.2.3 more tests on add_peptide() function add column cds_description to better understand why peptide_context is NA in sanity checks. Can be one of c("mutated cds", "truncated cds", "no mutated gene product", "no wt cds", "not in ORF")
