Handle XIOS contexts

Fixes #731.

This PR does several things:

Provide an enableXios utility that is used to configure across all tests.
Allow a context ID to be specified when creating an Xios instance, which allows several such instances to be created in the same run.
Separate the reading and writing tests by spatial dimension but combine them into one file.
Arbitrarily set an hour-long timestep for XIOS on initialisation, otherwise strange bugs can crop up.
Improve clarity of Xios::finalize docstring.

I haven't even tried to understand the finer points of the XIOS read/write test, but assuming that tests what needs to be tested, this all looks good.

The same test code is all still there, just in a different format. Thanks @timspainNERSC!
