v0.2.0

Breaking Changes

• RomanLowercase has been renamed to RomanLower for consistency.
• HiraganaAiueo and KatakanaAiueo have had Aiueo removed from their names
  to match the CSS naming and reflect modern expectations.
• Urdu has been removed. The Persian Unicode range is reused for Urdu
  numerals, and the different symbols are a result of using an Urdu or Persian
  font.
• DigitCollection::len and DigitCollection::digit now take a digit_index
  parameter, allowing a digit collection to delegate specific digits to other
  implementations.

Changed

• NominalString::INLINE_CAPACITY is now 62, and the type has been optimized to
  avoid zero-initializing data unnecessarily.

Added

• NominalString now implements Clone.

• NominalString::new_reverse() returns an empty string that is optimized for
  push_front operations.

• AdditiveSet is a new NominalSystem implementation that implements additive
  nominal systems. The existing Roman numeral implementation is now utilizing
  this type.

• These nominal systems have been added from the CSS counter-styles spec:
