Closes #234.
Add prop
key: (opt: T) => unknown = (opt) => `${get_label(opt)}`.toLowerCase()
which should map options to a value by which equality of options is determined. Used inadd(option)
/remove(option)
functions, which previously had hacky hard-coded equality checks.key
replacesduplicateFunc
which served a similar purpose but with a worse API. It also wasn't used inadd(option)
/remove(option)
even though arguably it should have been.This is a breaking change and will be released as v10.
