Implement a diagnostic coordinate transformation tool

[lemmatum]

Many photon-based diagnostics (e.g. radiography, x-ray spectroscopy, etc.) require applying corrections at different spatial locations of the instrument. For example, the filters are located in a different spot than the Bragg crystal, and the microchannel plate, the scintillator, the CCD, etc. I was listening to a podcast about AstroConda and one of the speakers mentioned that they have a tool for transforming between different spatial locations within a diagnostic for their telescopes. They can apply calibration corrections, make photometric simulations/estimates, and even apply point-spread functions to simulate the end to end instrument response to a given light source. I think it would be excellent if we could implement a similar type of tool, but more relevant for laboratory plasma experiments.

This could potentially eventually be integrated to the path/line integrated diagnostics framework proposed in PR #1123
