[New Script] Upgrade Champion Mastery

[Aluerie]

This should only use basic champion shards

Note: Riot hinted that they are going to rework Champion Mastery in a way where none of currencies (BE, OE, RP) gonna be involved with upgrading/levelling.

So maybe wait until then 🤷

it also means that Mass Disenchant Accounting for Mastery levels is pointless now.

Also Riot hinted that mastery rework goes live in either may or september so long wait awaits 😴

Actually kinda sad, my primary motivation for this tool was exactly Mass Disenchant Accounting for Mastery 😀
