Add Query helper methods

[patricklatimer]

OData (what the dataverse api uses) has lots of query options, like filters, order_by, top, ....

We could either list those out in a file like this:

equal: Callable[[str, str], str] = lambda column, value: f"{column} eq {value}"
not_equal: Callable[[str, str], str] = lambda column, value: f"{column} ne {value}"
greater_than: Callable[[str, str], str] = lambda column, value: f"{column} gt {value}"

Or maybe we could use the python-odata library to help us construct our queries (plus we get autogenerated table schema python code)
