You tell me, I'm ready to co-operate, thanks!

The language server was initially added by @buzztaiki — could you lend us a hand with it? Thanks!

It seems that workspaceFolders has become required since typeprof v0.30.0. There might be other places that require correction as well.
I'll make the fixes, so please wait a moment.

FIxed it just by setting multi-root to non-nil. It seems that the workspace is now ignored if typeprof.conf.json is not configured.
