Use https://github.com/shinh/elvm to transpile LZMA

### Problem

LZMA is not ported to all the languages we support (which is all the languages on LeetCode).

### Solution

Pick one implementation of the algorithm and transpile it using *ELVM*.

### Considerations

- more mainstream languages can be transpiled using LLVM
- between them, do LLVM and ELVM support all the LeetCode languages?
- will the transpiled code need to be optimised?
