INTER: liveview enhancemets

INTER are having a new detector installed June - it will be a pseudo 2D arrangement, there will be 8 modules that will each act as linear detectors providing spectrum v TOF, but will be placed side by side to give an extra dimension. Each module will have a special "unaccounted counts" spectrum. They would like several ibex liveviews of this:

* 8 separate spectrum v TOF views for the modules each in its own tab
* A single view showing all 8 modules (spec v tof) side by side horizontally (unless they look too small, then think again)
* A single spec v TOF view of the summed counts from all 8 modules
* A 2D integrated counts over TOF view of spectrum number v module number (1-8)

In addition they would like an enhancement to the current DAE single spectrum view:
* A view similar to the current counts v TOF graph for DAE spectra, but with the option to have multiple spectra on a single graph. See https://github.com/ISISComputingGroup/IBEX/issues/7699

They also mentioned a few issues with the current spec v TOF live view - these probably relate to the axes not reflecting the true spectrum or tof value, but rather a pixel number starting at 0:

* After zooming spectrum number is inaccurate
* TOF on spec v TOF is bin number not real TOF

Start by reviewing the existing DAE single-spectrum and spec v TOF live views. Confirm how module spectra, summed counts, unaccounted counts, spectrum numbers, and real TOF values are currently represented. Done requires an agreed design and implementation plan covering the requested module views, multi-spectrum DAE graph, and corrected axes.
