[Media] fast-h2m: High-performance HTML to Markdown converter

It is a converter from HTML to Markdown (what LLMs eating). Orignally from https://crates.io/crates/html-to-markdown-rs which is a vibe-coded repo with some of inefficient decisions inside. My fork is mostly a clean up.

To make this library even faster I also forked astral-tl to make zero-copy parsing and enhance that code to latest Rust.

- It has python 3.8+ bindings under the same name on PyPI.

- Library supports SIMD if you really need gain of 5-10% in parsing
