feat: icrc21_canister_call_consent_message for ledger-icrc (#710)
# Motivation Add support for `icrc21_canister_call_consent_message` to `@dfinity/ledger-icrc`. # Notes It annoys me a bit that the close basically duplicates the code of ICP (provided in PR #709) but, not sure it is worth the effort at this point to create a util or even lib for that particular topic. We might do so if more canisters starts implementing consent message but, happy to hear any thoughts about it. # Changes - Expose and implement new function `consentMessage`. - Add a new parameter for the request. - Map the potential error. --------- Signed-off-by: David Dal Busco <david.dalbusco@dfinity.org> Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>
