Improve the TusPatchResponse to include the upload result.

[Haeavar]

Currently its quite difficult to handle a failed upload using TusPatchWithChunkAsync. If the upload fails while uploading a following chunk it returs the response of the previous (succeeded) chunk. If I now check the reponse for succeeded statuscode its not correct. I would need to check the size as well 8as you do it in the OnCompletedAsync callback.
Using the OnCompletedAsync callback to check for a suceeded call is a lot lines of code to write. If you could add a bool property 'UploadSuceeded' to the TusPatchResponse I could check easily for a succeeded call.
So, at the end of the TusPatchWithChunkAsync method just add following line:
tusPatchResponse.UploadSuceeded = (totalSize == uploadedSize);

Than, a caller could just do like that:
var result = await httpClient.TusPatchAsync(tusPatchRequestOption, cancellationToken); return result.UploadSuceeded;
