Soil ID: Compare user's color data to wet or dry profiles, depending on user input

[DerekCaelin]

The NRCS Official Series Description contains color data at horizons for both wet and dry soils (link), but the algorithm only compares while dry (us_soil.py, 504-506) .

Many soil scientists characterize while the soil is wet, and would not want to dry soils as a part of their practice. So, we could improve the quality of our soil id recommendations if we fetch both the wet and the dry colors of soils, and let the user's flagging of wet and dry decide which we use for the comparison.

Acceptance criteria

• As a user, I want to define whether soil is moist or dry
• Depending on which, the soil id algorithm pulls the appropriate data from NRCS Official Series Description and references that when doing a comparison of LAB colors.
