Couchbase Lite parsing nested value as UInt64 then throwing exception on update.

Expected behavior

Either value should have been parse by couchbase lite as a uint rather than UInt64 or couchbase lite should accept UInt64 as a valid upload type (maybe cast under the hood?).

Actual behavior

Couchbase lite parses non floating type values as UInt64 which then are rejected when an update is requested. (See method mutableDoc.SetValue(key, value);).

Steps To Reproduce

1. Create a dictionary where one of the values is another dictionary that has at least one whole number as a value. This can be passed in as a double but when it is uploaded to couchbase server it will have no decimal points in the json.
2. Get the document you’ve created using the couchbase id and get the dictionary from it using document.ToDictionary();
3. Dont change the number value in the nested dictionary but still use the mutableDocument SetValue method to update the nested dictionary value. You will see the crash.

@djpongh Can I sneak this into 2.1? It’s very small but saves a lot of hassle if it’s there. All that is required is adding a type to the list of acceptable CBL types.

Well I added the type anyway, and added a test to make sure that ulong can be inserted. However, there is no API to directly insert ulong so if it exceeds the signed 64-bit max value the only way to retrieve it will be through the untyped GetValue
