Feature request: Compile for ARM64

[Charmandrigo]

This is a pretty optional request but would be great to see. I have a Samsung Galaxy Book2, a windows tablet that runs on a ARM64 processor, while Windows 10 on arm can already run x86 applications and it's possible to install Drawpile that way, it would be nice to see Drawpile properly compiled for Windows ARM64 so it runs natively on this version of windows without having to emulate the intel x86 architecture
