Account for different HLA-B variants

[tamslo]

One tile per positive/negative variant.

Could change this in the source data, but then we would probably also need to adapt how lookups are made; therefore it might be cleaner to handle in the app:

• Adapt test data to include multiple HLA-B variants
• Rename Diplotype to GeneResult
• Rename CpicPhenotype to CpicLookup
• Make GeneResult and CpicLookup inherit from abstract class Genotype
• Move PhenotypeInformation to own file (not really required for this ticket but should do this when already refactoring) ➡️ added to Refactor User Data #680
• Fix fetching lookups
  • Somehow, the .fromJson factory is only called later, but at this time the json was already adapted in place at that point
  • Fix by not changing json in place but passing new object to internal FromJson constructor
• Rename CpicLookup to LookupInformation
• Refactor to not write gene results and lookups into map with gene as key; need get all information not by gene but gene plus variant / genotypeKey either change to list or adapt keys of map
  • Instead of LookupInformation store GenotypeResults (implements Genotype; stores relevant information from GeneResult; stores lookupkey) as genotypeResults in Map with genotypeKey
  • Rename GeneResult to LabResult and geneResults to labData
  • Better name for GenotypeResults, e.g., something PGx-related? GenotypeResult is pretty accurate
  • Use genotype key as title and only "positive" or "negative" as phenotype / genotype
• GenotypeResult should have extension to easily get overwritten lookup; possible to include or combine with PhenotypeInformation? (moved to Refactor User Data #680)
• Test that everything works
  • Linking to gene detail page
    • Non-unique gene
    • Unique gene
    • Not tested
  • Filtering drugs
    • Non-unique gene
    • Unique gene
    • Not tested
  • Lookup matching to guidelines (including source URLs)
    • Non-unique gene
    • Unique gene
    • Not tested
  • Inhibitors working
• Fix that phenotype shows on guideline card multiple times
