Support more sampling rates

[rouzbeh]

The python package now supports more sampling rates (32, 64, ...). The specific downsampling is done
here

I believe this could be ported to R.

Thanks for the update, Ali. We don't currently use any devices that allow for those sampling rates at the University of Kansas. Do you have any files that you could share that would allow me to translate the code and check the results with Actilife-generated output?

We have a few tests in the python package. For instance, this input should result in this output. There are also tests for intermediate steps here.

Thanks! I'll check it out and let you know if I have any questions.
