HTML lexer/tokenizer

[BjornRuud]

Here is a (high-level) lexer for HTML that I use for parsing strings containing HTML elements for formatting. Feedback is much appreciated.

I initially had a handcrafted parser doing this work and I struggled to get the swift-parsing version to perform at the same speed, but this final version is actually ~3x faster and uses less memory so I'm definitely reaching for swift-parsing for my future parsing needs.

Example: The string "A <b>bold</b> move" will output

[
  .text("A "),
  .tagStart(name: "b", attributes: [], isSelfClosing: false),
  .text("bold"),
  .tagEnd(name: "b"),
  .text(" move")
]
