[enhancement] Support "VS Code Comment Anchor" style comment syntax?

[hozza]

I've not created a PR yet, as I'm not super familiar with ST4 plugins or this code base and this is more a config enhancement suggestion.

A fair amount of projects use the comment/anchor syntax from Starlane Studios Comment Anchors plugin for VS Code. I've built a config to support this sort of comment highlighting into Colored Comments for SublimeText.

I copied their colors and identifiers from here.

File: colored_comments.sublime-settings (P.S. it would be nice to be able to append to "tags" rather than overriding it completely and having to include the defaults manually also, maybe use a "tags" for default and merge in a "custom_tags" from the user file?)

{
  "tags": {
    // SECTION defauls included
    // Friendly name for you to know what the purpose is
    // and used in the OrderedDict
    // These should be unique
    "Important": {
        // The name of the scope being use in your color scheme file
        "scope": "comments.important",
        // The actual identifier used to highlight the comments
        "identifier": "!",
        // Enables sublime.DRAW_SOLID_UNDERLINE
        // Only noticable if outline = true
        "underline": false,
        // Enables sublime.DRAW_STIPPLED_UNDERLINE
        // Only noticable if outline = true
        "stippled_underline": false,
        // Enables sublime.DRAW_SSQUIGGLY_UNDERLINE
        // Only noticable if outline = true
        "squiggly_underline": false,
        // Enables sublime.DRAW_NO_FILL
        // This disables coloring of text
        // and allows for the outline of the text
        "outline": false,
        // Treats the identifier
        // as an regular expression
        "is_regex": false,
        // Enables ignorecase for the ideentifier
        "ignorecase": true,
    },
    "Deprecated": {
        "scope": "comments.deprecated",
        "identifier": "*",
    },
    "Question": {
        "scope": "comments.question",
        "identifier": "?",
    },
    "TODO": {
        "scope": "comments.todo",
        "identifier": "TODO[:]?|todo[:]?",
        "is_regex": true,
        "ignorecase": true,
    },
    "FIXME": {
        "scope": "comments.fixme",
        "identifier": "FIXME[:]?|fixme[:]?",
        "is_regex": true
    },
    "UNDEFINED": {
        "scope": "comments.undefined",
        "identifier": "//[:]?",
        "is_regex": true
    },
    
    // SECTION VS Code Comment Anchors Syntax Support

    "ANCHOR": {
      "scope": "comments.anchor",
      "identifier": "ANCHOR",
      "ignorecase": true,
    },
    "STUB": {
      "scope": "comments.stub",
      "identifier": "STUB",
      "ignorecase": true,
    },
    "NOTE": {
