Set of changes to the daemon to support additional sample rates and to enhance the test suites to verify with 192Khz and 384Khz

The build script has been modified to checkout the driver branch aes67-daemon-issue11 with fixes to support sample rates higher than 192Khz.
These changes fix #124 and #122
