feat: dict based Hyphenation (#305)
## Summary * Adds (optional) Hyphenation for English, French, German, Russian languages ## Additional Context * Included hyphenation dictionaries add approximately 280kb to the flash usage (German alone takes 200kb) * Trie encoded dictionaries are adopted from hypher project (https://github.com/typst/hypher) * Soft hyphens (and other explicit hyphens) take precedence over dict-based hyphenation. Overall, the hyphenation rules are quite aggressive, as I believe it makes more sense on our smaller screen. --------- Co-authored-by: Dave Allie <dave@daveallie.com>
