cd00d7f724 test PSA key derivation: add positive and negative cases for mixed-psk
Mix-PSK-to-MS test vectors are generated using python-tls library:
https://github.com/python-tls/tls

Steps to generate test vectors:
1. git clone git@github.com:python-tls/tls.git
2. cd tls
3. python3 setup.py build
4. sudo python3 setup.py install
5. Use the python script below to generate Master Secret (see description for details):

"""
Script to derive MS using mixed PSK to MS algorithm.

Script can be used to generate expected result for mixed PSK to MS tests.

Script uses python tls library:
https://github.com/python-tls/tls

Example usage:
