Feature request: Support `raise_on_no_idempotency_key` for `idempotent_function`

Use case

Trying to use idempotent_function in an “optional” manner. Example:

import random

@idemp_f(data_keyword_argument="key")
def echo(key: str = None):
    return random.randint(1, 1000000)

When called like echo(key=None) will raise RuntimeError, even when raise_on_no_idempotency_key is set to False

Solution/User Experience

Unless there is good reason not to respect the IdempotencyConfig.raise_on_no_idempotency_key value. Perhaps adding a similar parameter to idempotent_function like raise_on_no_data_keyword_argument or something to that effect.

Sorry for late reply, just seeing this now – I was unsure of if this was unintended side effect (bug) or a feature 😃. Thanks for the swift resolution, much appreciated.
