Changelog

• Adds a new unit construction method that allows for more complex units involving math, symbols or basically anything.
• ⚠️ Breaking Change: The rounding setup has been streamlined. The mode can no longer be none, instead it defaults to "places" while the default precision is none meaning that no rounding is applied. This is more convenient when rounding single numbers (e.g., num(round: (precision: 2))[9.80665]) because the mode does not have to be set repeatedly.
• Fixes an issue with non-breakable units and quantities.
