Native LimeSDR support
Currently, LimeSDR is only supported indirectly via UHD -> soapy-uhd -> soapy -> limesuite
It is difficult to debug the stability issues we're seeing in such a complex stack, so it would be great to have a native LimeSuite backend to avoid the complex stack.
This would also have related usability benefits, i.e. users don't need to install a whole bunch of dependencies and make sure they're configured accordingly.
