EnsembleConfig::devices in Swig/python.

[ptheywood]

CUDAEnsemble::EnsembleConfig::devices is a std::set<int>.

This does not appear to be well-wrapped by swig currently, so is not (obviously) usable from python (other than via the CLI)

The current command line argument takes a comma separated string of non-negative integers, which is parsed into a std::set.

Although uniqueness is useful, it might be worth using an order-preserving data structure (although probably not neccesary). This might also help if Swig is not great with sets, as we know it's usable with vectors. It could then be converted to a set at time of use.

swig has a std_set.i file, so it might just need to be included.

Found in _deps\swig-src\Lib\python

Have fixed this, PR coming soon.
