[Feature Request] Built-in Resource Pack Converter (Java .zip -> Bedrock .mcpack)

[Andrew-J-Larson]

Assuming #518 is something of a possibility in the future, maybe it would be nice to have a built-in resource pack converter in the launcher too (though, of course, with the warnings that not all resource packs will convert well, or at all).

I'm sure https://github.com/GeyserMC/PackConverter would be a good for a starting point, although it's coded in Java (which they referenced basing code off of a now defunct repo, but there appears to be a fork of it that was last updated 6 months ago -> https://github.com/xanthousm/ConvertJavaTextureToBedrockApi).
