Request: Scanning filtering by manufacturer ID

This is a feature request, but we recently had to abandon our use of this library due to not being able to scan filter by manufacturer ID (at least on Android, don’t know what iOS world looks like). I had added the functionality locally to the library just by passing through a manufacturerID and calling if that value was provided

                ScanFilter.Builder builder = new ScanFilter.Builder();
                builder.SetManufacturerData(manufacturerId.Value, Array.Empty<byte>() );
                ScanFilter filter = builder.Build();
                scanFilters.Add(filter);

Thanks for the suggestion. That’s a reasonable request.

Apart from filtering on Manufacturer data, it would also be good to have a way to filter on Service data. Right now one can only filter on Service UUID (by passing it directly to IAdapter.StartScanningForDevicesAsync).

Given all those different filtering options (cf. https://developer.android.com/reference/android/bluetooth/le/ScanFilter.Builder), it would be good to introduce more advanced filtering mechanisms to IAdapter.

And yes, one should also check the iOS APIs, in order to see what we can cover across platforms here.

Service-data filtering was added with #588.
