Enhancement: Support for TotK and updated engine

[jedinjapan]

With the mod scene around TotK growing, there is gaping hole for a mod manager that can handle RSTB and mod file merges and support a mod format that allows merging diffs only. With most mod merges currently being done by hand, or not at all things area mess. This is compounded by the RSTB being updated with each game version, causing mods to fail spectacularly between versions. While currently mod authors are releasing with multiple compatibility versions, this is... untenable long term.

Broadly speaking, the basic formatting in TotK appears similar to BotW, and while additional check may be needed to support those changes, it would be good to know if U-King could grow to support this TotK as well.
