[PATCH v3 05/23] utils: tuning: Add requirements file and update readme

[Stefan Klug]

Add a requirements file to ease the installation and use of the tuning
scripts. Document that in the readme. No debian packages are provided as
rawpy is not packaged as deb. So pip has to be used anyways.

Also add pyyaml which was missing in the dependencies.
