Problem with building for WASM/WASI target

[orzel7]

I've tried to build this code to web assembly, and it fails:
`

I realize tinygo is not 100% compatible with go, but if this project claims to be WASM compatible, it would be nice to take a closer look at the problem

Maybe try with the latex build tag, that would use the system's LaTeX implementation. Does that work?
