nitro-input v0.3.2

• keepPlaceholder: the rest of a mask's placeholder stays visible,
  greyed, after what has been typed ("1234 5" then "678 9012"); without a
  placeholder the mask itself is shown, empty slots as
  maskSlotPlaceholder (_): +1 (212) ___-____. Plain and reflowing
  fields, both platforms.
• maskAffinityFormats and maskAffinityStrategy: several patterns
  for one field, the best kept on every edit (a 4-6-5 Amex card beside
  4-4-4-4). Compared on the value characters, and a tie keeps the format that
  is showing, so the grouping does not flip back and forth while typing.
• maskTextCase uppercases or lowercases letters as they arrive, and
  maskCharacterMap replaces characters before masking (Cyrillic
  look-alikes, a comma for a dot).
• Letter slots ([A], [a]) take letters beyond ASCII: Latin with
  diacritics, Greek, Cyrillic, Armenian, Hebrew, Arabic, Devanagari, Thai,
  Hangul, kana and CJK.
• A paste that repeats a mask's leading constants ("+63…" into
  +63 [000] [000] [0000]) loses the repeat when it would otherwise overflow.
• Fixed: a constant the mask inserts right at the caret now puts the
  caret after it when typing and before it when deleting (the gravity was the
  wrong way round), as RedMadRobot's input-mask does.
• Fixed: an ellipsis after an optional slot ([9…], [a…]) repeats that
  slot; the format sanitizer used to move it to the front, where it took any
  character.
• Fixed (iOS): changing mask (or a number format) re-masks the text and
  reports it through onChangeText / onChangeMask / getText(), as Android
  does; the field showed the new text while JS kept the old one.
• The mask engine is checked against ~1,900 cases ported from RedMadRobot's
  input-mask (Android and iOS), maska and react-native-advanced-input-mask.
