fetchOSD and related functions should return series names in title case

tools::toTitleCase

Possibly change the API:

get_OSD() and the SoilKnowledgeBase OSD JSON files also return series names in all caps. I added a TODO to switch series names to title case. (ncss-tech/SoilKnowledgeBase#25; see for example https://github.com/ncss-tech/SoilKnowledgeBase/blob/main/inst/extdata/OSD/E/ECKRANT.json)

However this change strikes me as something that could wind up causing problems with backward compatibility. I am pretty used to these returning series name in all caps. And the file names are in all caps.

Yeah, I'm not sure about the original justification. There are so many example of using upper case that broad-scale conversion to title case isn't warranted. Closing.
