iRule Developer Tools

This is now published on https://marketplace.visualstudio.com/items?itemName=bitwisecook.tcl-lsp

I'll look into publishing the other editors (Sublime, Zed, Jetbrains etc) when I can.

I'm thankful to those who've reported issues to me already, please, if you find any issues, like editor bugs, diagnostics or optimisations misfiring, create issues on https://github.com/bitwisecook/tcl-lsp
