[Feature Request] Add (parsing) errors to LSP

[Achtuur]

One of the most useful features of lsp's is that you can see (syntax) errors as you're typing. From a cursory glance it seems that this project is capable of parsing glsl, but it doesn't report parse errors through the lsp protocol. Based on this, I would assume it is doable to add error reporting.

A more advanced version of this feature could use glslc to get compiler errors, but parse errors are a good start I think.

Any plans to add this? I think I might look it up, and make a PR if no one else has already started doing it.
