Suggestion: export materials list as .txt

[Sukasa]

The materials list is great, but sometimes when working on larger builds it would be nice to be able to download it as a .txt file to use as a checklist while gathering materials. If this exists I apologize, but I was unable to locate it.

this would be especially helpful if we could export the max split material lists, since litematica can't really do anything like that at the moment, and having to go through each map's material list my hand is tedious and VERY error prone XD
