wordpiece 2.1.3

• Implemented various speed improvements, improving speed and memory usage by over 1000x. (#27, @jonathanbratt)
• Removed purrr dependency. (#30, @jonthegeek)

wordpiece 2.0.1

• Refactored wordpiece_tokenize to accept a character vector with length > 1. This makes the package more usable within a workflow, but will break scripts that used the previous version (the output is now a list of character vectors, instead of a single character vector). (@jonthegeek)
• Added a pair of default vocabularies via the {wordpiece.data} package. (@jonthegeek)
