Function numberEnumToNumberVal

Returns the validated & existing number value part of a "numeric" enum (the right hand-side), given either side (the string or number part) of a "numeric" enum.

Features / Notes:

The number part can be given as a number or parseable string number.
The string part can be given the exact string key, or lower, upper or capitalized form of the string. // @todo: make this optional
It should maintain the right types of Enum / Enum keys, eg keyof TEnumType as a string

See

z.numberEnumToStringKey() for the reverse function

@todo: Curry this function, maintain types:

_.curry, return type is string, instead of keyof TEnumType
@miyauci/curry not working at all, types are lost
