Fix #2467: Typescript use enums for options

Using Typescript enum is the more correct way to represent these options

[jafin]

Would you consider preferring union types instead of enums?

and

for justification.

@jafin this will probably be Primetek's preferred approach to use union types as that is how all of the rest of the code base is. However it was curious they chose to go this Interface route with static read-only when from reading their examples it LOOKS like they wanted an enum for FilterMatchMode.IN etc.

Thoughts?

[jafin]

@melloware if existing code follows a convention, I assume that would be the approach.

Thank a lot, @jafin and @melloware! For now, the 'enum' definition seems appropriate for this issue. I'll talk to our team for improvements.
