v5.6.0

• New optimizations #255

  • re-use a unique result object for all methods but parse(...)
  • remove memory allocation + callback in packed hash
  • remove unnecessary calls to indexOf and lastIndexOf in packed hash

  These optimizations result in up to 20% faster invocations of parse(...)
  and 40% faster invocations of getPublicSuffix(...)when using
  tldts-experimental. This should also reduce memory pressure in cases where
  specific methods are used (i.e.: all but parse(...)) since no intermediary
  result object needs to be allocated.
