PHI instrument having wavelength data in multiple units in SOAR.

[NucleonGodX]

Provide a general description of the issue or problem.

From the SOAR side for the PHI instrument, we get wavemin and wavemax values. These values can be fetched and shown in sunpy-soar in an Astropy table, but they are provided in two different units, i.e., angstrom and nanometer. Consequently, the values sometimes differ greatly. For example:

Value of wavemin: 6172.948
Value of wavemin: 617.3639
These values are of the same order but are in different units. However, this is not mentioned anywhere in the SOAR data. If the units could be standardized, it would be easier to implement in sunpy-soar.
