integration with linter

I think it’d be really cool if this package could integrate with the linter package (as well as having a setting to disable its own error display).

This way, it would benefit from a unified experience for visualizing and being able to jump to errors in projects, as well as allowing errors to be displayed in the minimap without much effort.

Looks good! I'll see if I can do this after branch ocaml hits master!
