chore: refactor json logic evaluator to pass custom operators as options

[bacherfl]

Closes #667

This PR moves the registration of the custom JSON evaluators out of the NewJSONEvaluator method, and allows to pass the custom evaluators as options to the New function. This way, the JSONEvaluator does not need to be aware of the custom evaluations and reduces its responsibility to just providing the means to execute jsonLogic evaluations, based on its store and the flag configurations.

FYI I think the lint error that's appeared is a bug/false positive.

Unfortunately cannot reopen the PR. This is discussed here : isaacs/github#361

let's open a new PR to get this through

Yeah, my bad. I thought closing and reopening the PR would fix the GitHub action issue.
