No API to add a language/custom highlightr js source

[SoylentGraham]

I want to highlight a language that highlightr.js supports, but is not in this/https://github.com/raspu/Highlightr 's minified build of the js lib.

https://github.com/raspu/Highlightr seems to support a custom highlight.js build, in it's constructor, but I'm not seeing a way to set this up with this package.

I presume that is the intended approach of using specific/additional languages, so the swiftui interface needs a way to pass the highlightr lib path down the chain

Steps to make custom language build

• git clone https://github.com/highlightjs/highlight.js
• npm install
• Copy https://github.com/highlightjs/highlightjs-wgsl/blob/main/src/languages/wgsl.js to highlight.js/src/languages
• node tools/build.js -n wgsl

Then to integrate with my changes

• Add new build/highlight.js to app
• mv highlight.js highlight_wgsl.js

// global
let highlighterInstance = Highlightr(highlightPath: Bundle.main.path(forResource: "highlight_wgsl", ofType: "js") )
// in view
CodeEditor(source: $layer.source, language:CodeEditor.Language(rawValue: "WGSL"), highlightr:highlighterInstance)

Also needed to change dependency of Highlightr to use 2.2.1 to support builds from the current version (11.10.0) of highlightr.js
