[evancjohnson]

Is this something you are un-sure about or want help with? If so please use the discussion feature. We can always create an issue after some discussion later if required 😊

Is your feature request related to a problem? Please describe.
I would like to use the IPatchOperationBuilder to increment a property on a document without reading it first.

Describe the solution you'd like
Expand the IPatchOperationBuilder to support additional patch operations, starting with Increment

Describe alternatives you've considered
Currently I am writing patch operations (outside of replace) manually and would like to use the library to help with that information.

Additional context
I looked to see if this was requested before and I did not see anything referencing Increment directly, if this is related to another issue, please let me know and I can close this.
