Modded Leaderboard Patch (#7)

* Change to .user File

* I hate patching async methods

this took me 2 hours

* Change async method finder location; added more transpiler patches

* Attempted patch - commit for history

* Changed to much simpler & compact method

kept async method finder function for future usage

* Changed to Lord's GameLibs; Updated Leaderboard Patch Respectively

* remove file left from user stuff

* Added older sdk support

* Lowered patch priorities

Allows other mods to override the prefix patch before it is ran - as these patches only change the parameter based on specific circumstances that would be changed by another mod

* Shortened Leaderboard Patchfile

Done so by publicizing game assets from GameLibs

* Change Binding Flags

* Fix incorrect patch

* Minor Refactoring & Reorganization
