LoadNexusLogs now extends NexusHDF5Descriptor
Allow HDF5 open to handle multiple handlers in NexusHDF5Descriptor

Expose m_fileInfo from NexusFileLoader

To do:

This means we can hide the parsing function that takes an xml string from the public interface and add a friend class to test this.
It also means that getRuns() can be called multiple times with different criteria without having to re-parse the file.

In places other substitutions have been made, e.g
Clang does not yet specialize std::shared_ptr for T[]. Vector

Adds a couple of generic functions for requesting data from a journal. The main work is done by a function that takes the file contents as a string so that this can be easily tested. A wrapper function allows the file to first be fetched from a URL constructed for the instrument and cycle.

Also adds a couple of functions for requesting the list of cycles, again with one function taking the file contents and another which finds the URL for the instrument.

Operators provided for LogManager, PropertyManager, Geometry and Run alongside testing

Previously, if an attenuation factor was requested for a lambda that
is outside the range of an explicit attenuation profile the code
extrapolated based on the gradient of the two most extreme points.
If the data was noisy this gave some poor results. Improve this by
falling back on the tabulated linear absorption coefficient of an
optional ExtrapolationMaterial
