litematic support

**Is your feature request related to a problem? Please describe.**
Since the change from 1.12 => 1.13+ using schemtaica to create new schematics is a no go.
Litematica is now the 'way forward', but there is no support for litematica

**Describe the solution you'd like**
Be able to paste and export to .litematic file types, just like we can with .schematic files

**Describe alternatives you've considered**
NA

**Additional context**
I know a couple of people are looking as I have, I saw on curseforge that request should be made here.
