updated alleles based on PharmVar update: Update of alleles:
• *18, remove 578T>G (L193R) 
• *21: add L643F (1929 A>C, rs34671512)
• Rename *1A to *1
New rows (new alleles):
• Add row *37: *1B re-assigned as *37
• Add row: *38 (old *1c), 
• Add *39, *40, *41, *42 (*39-*42 from new sequence submissions)
New columns (core alleles from new submission):
• Add column: for R152L for *38 (no rsID yet, the one at the chr location show as G>C instead of G>A https://www.ncbi.nlm.nih.gov/snp/rs145144129)
• Add column: Splice donor for core alleles from *41 from new submissions
• Add column: Y173C for core alleles from *42 from new submissions
• Add column: R253X for core allele from *39
Remove rows (merges):
• *1B: reassigned as *37
• *17: merged *17 with *15 (-910G>A removed)
• *18: Merge *18 with *14 (L191=, F199=, S137= removed from core allele definition)
• *21: Merge *21 with *20 (-910G>A removed)
• *22: Merge *22 with *19 (L191= removed)
• *35: Merge *35 with *20 (F199= removed, no information for F199=)
Remove columns:
• Remove column: rs4149015 (-910G>A) from allele definition table (pass 500 upstream of exon 1)
• Remove column: 578T>G (L193R), since *18 no longer have this
• Remove column: L191= (rs4149057) from core allele definition, synonymous change
• Remove column: F199= (rs2291075) from core allele definition, synonymous change
• Remove column: S137= (rs11045818) from core allele definition, synonymous change
