Subject: feat(web): add frequency, parse_cards and eval_hand functions
X-Git-Url: https://git.beaudet.xyz/?a=commitdiff_plain;h=fc2e651c563bd214f50e7eb26906ad83c3203e2c;p=poker-eval.git

feat(web): add frequency, parse_cards and eval_hand functions

Does not use deprecated `eval_from_str` exported wasm functions anymore.
Updated the wasm_bindgen generated files
