Feature request: LZMA compression and decompression

[d-Rickyy-b]

Is your feature request related to a problem? Please describe.
I am currently working with nsis installer files. These seem to use lzma compression a lot. I'd love seeing a de/compressor operator for that.

Describe the solution you'd like
Implement a new lzma de/compressor operator. There even seems to be a javascript implementation already: https://github.com/LZMA-JS/LZMA-JS
