v0.4.0

• FormatElement now borrows a &str instead of owning a String, leading to fewer allocations and a significant performance improvement (PR #10, thanks to Samuel Collins (Humandoodlebug)).
  • this is a breaking API change to the lower-level v0.2 API
  • the original and primary (v0.1) API is unchanged
