input_frames_used returned by src_process may be less than the number of input frames

	(error, input_frames_used, output_frames_gen) = src_process(
	self._state, input_data, output_data, ratio, end_of_input)

Currently input_frames_used is ignored.

This problem prevents python-samplerate to work correctly if the resampling ratio does not divide the block size provided to Resampler.process.

PR #6 is an attempt to fix this issue.

@tuxu: what would be the timeline for making a new release?

Thanks for the PR, @hcab14! We can upload a new release to PyPI just after your changes are reviewed and merged into master.

Thanks a lot for your response!

Somehow this problem was not caught by the tests, so it'd be good to have a test case for that. I can start thinking about that.

BTW: the documentation for python-samplerate is very good.

@tuxu: did you have a look at the changes?

The motivation for these changes comes from here where currently only a few resampling ratios are supported due to this issue.
