26.1 support

[xvrrv]

well i updated the mod to work on newest version xd
mostly was rename stuff and imports and methods
now i know its bad and you probably want to rewrite rendering but at least the mod is fully funtional and no bugs so far
i tested using sodium as well and no problems

up to you if you want it no worries xd

new feature: a way to convert coords between nether and overworld

• better coords handle so it will not re-convert the original coords, which caused the waypoint to move a few blocks of the original place
• improve conversion by using "round" so it will show nearest integer

close #58

new features:

• setting for max number of death waypoints; will delete old ones if max number reaches
• permanent death waypoint: will keep this one no matter if you reach the limit (will still delete older and ones which are not permanent)

closes #65 and #70

needs to update other translation but idk other languages but this will not get merge at all anyways xd
idk if its okay all this but it works fine xd as always you can use it for reference if you dont want to
