Leveraging hasSeasonality

[CommonClimate]

Seasonality is a property of the ProxyRecord class, which can presently only be specified (e.g. by passing a list), but not derived from LiPD files. We need a way to pass this through the cfr API if the field is present in a data frame. Known challenges:

• translating LiPD speak (e.g. 'Jan Feb Mar') to cfr speak ([1 ,2 ,3]).
• some LiPD files may contain many metadata fields called "Seasonality" -- apparently, hasSeasonality is the most relevant.
• create appropriate test

Note that for the first bullet point, the regex solution coded by Albus Shang for DOCU-CLIM does a fine job, so it should be easy to adapt.

Problem #2 is going to go away soon. Part of the deprecated properties. The seasonality I queried will be the correct one down the line.
