textrecipes 1.0.2

• Setting token = "tweets" in step_tokenize() have been deprecated due to tokenizers::tokenize_tweets() being deprecated. (#209)

• step_sequence_onehot(), step_dummy_hash(), step_dummy_texthash() now return integers. step_tf() returns integer when weight_scheme is "binary" or "raw count".

• All steps now have required_pkgs() methods.
