add docs, move some data fetching to more appropriate class
remove old XP memecrypto support handling, was previously removed due to
net standard/core split
refactor memecrypto to handle multiple save sizes (USUM won't be the
same size save file); placeholder -1 for USUM size
pkm editor, sav editor, menus, and a manager to glue the storage slots
together
decouples the pkm/sav editors from a static savefile reference.
improves dragdrop/click view/set/delete indication, hides unavailable
contextmenuitems, and fixes a few incorrect references. Box Subviewer
slots now have all the indication/events that the main save editor slots
have.
pls report behavior bugs 👍
