302: WIP: Support tracing lsp requests. r=DJMcNab a=DJMcNab EDIT: We need to work out a better way to handle settings before this can be merged. Help wanted TODO: Debug why decorations are sent even when highlightingOn is disabled This makes the log volume so high its impossible to work with anyway. (Continuation of #84 [#99 only disabled using it, not making sure we don't send it]). These logs can be used in https://microsoft.github.io/language-server-protocol/inspector/ Co-authored-by: DJMcNab <36049421+djmcnab@users.noreply.github.com>
