Is your feature request related to a problem? Please describe.
I see examples in documentation around specifying an allow_list when invoking the analyzer, but it doesn't seem to be exposed via the REST interface.

Describe the solution you'd like
Expose the allow_list in the body of the AnalyzeRequest POST.

POST /analyze

{
    "text": "John Smith drivers license is AC432223 and the zip code is 12345",
    "language": "en",
    "score_threshold": 0.6,
    "allow_list": ["John"]
}

Describe alternatives you've considered
None

Additional context
I'm using Presidio in a REST format as the code I'm writing is not written in Python.
