convert all dictionaries to char-byte instead of string (saves 50KB on
compressed dll, lul)
update OT string comparison for pre/post transfer specimens
Showing "TRAINER" for all languages isn't correct, just show a mapped
character
Closes#2049 , thanks @egzonqj & @WEERSOQUEER !
Checks.cs initially started out small, but over the years it has grown
to handle multiple types of checks. With all these checks next to
eachother, it's hard to see the overall groups. Splitting them up
(potentially further?) allows for more focused maintenance &
understanding.
Not sure if I'm happy with the overall bandaids used (checks no longer
done within LegalityAnalysis so variable repointing is excessively
used), but I'm happier the way it is now compared to the huge Checks.cs
