The previous implementation of parsing ingredients was very simple. I now wrote a parser
that I would consider good. It takes care of several edge cases and notations.
- Supports fraction unicode (½, ¼, ⅜, ...)
- Supports notations like `1½` and `1 1/2`
- Supports unit directly after the amount without space inbetween (`2g`, `2½g`)
- Supports notes (`5g onion (cubed)` -> amount: 5, unit: g, ingredient: onion, note: cubed)
- Supports notes (`5g onion, cubed` -> amount: 5, unit: g, ingredient: onion, note: cubed)
- Does not break when both commas and brackets exist
