Import from XLSX instead of CSV for isolate name formatting

[MaybeJustJames]

Some isolates have names that need to be partially italicised. One option for doing this is to read rich text directly from XLSX. Here are some potential resources:

• https://hackage.haskell.org/package/xlsx
• https://github.com/nkpart/xlsx2yaml
• https://hackage.haskell.org/package/xlsx-0.8.4/docs/Codec-Xlsx-Types-RichText.html#t:RichTextRun
