Draft: Allow lowering the chunk_size on Resampler

[obsoleszenz]

ATTENTION: This is just me playing around with the codebase, i have no idea of the math ^^

This extends the Resampler trait with:

• fn set_chunk_size(&mut self, chunk_size: usize) -> ResampleResult<()>;
• fn chunk_size(&self) -> usize;
• fn max_chunk_size(&self) -> usize;

ToDo:

• Currently this calculated an invalid needed_length after the first processed frame
• Rebase on top of Use test_log::test to have env logging in all tests #80
• Remove weird default implementations

This functionality is included in the v0.16.0 release.
