Description

In scipp/essdiffraction#55 the computation of d-spacing from calibration was effectively removed because we needed the wavelength, 2theta coordinates for adding masks.
We should be able to compute them from the final d-spacing, by first altering the detector positions?

Research direction

Start by reviewing the computation history in scipp/essdiffraction#55 and trace how calibration produces the final d-spacing. Determine whether detector positions can be transformed to recover wavelength and 2theta coordinates for masks. Done means those coordinates can be computed reliably from the final d-spacing.
