Add data from Jordan & Shennan 2009

[joeroe]

Includes four datasets on basketry, cradles, ceremonial dress and earth-lodges from hunter-gatherers in Northeast California.

• Jordan, P., Shennan, S.J., 2009. Diversity in hunter–gatherer technological traditions: Mapping trajectories of cultural “descent with modification” in northeast California. Journal of Anthropological Archaeology 28, 342–365. https://doi.org/10.1016/j.jaa.2009.05.004

The basketry data was previously published by Jordan & Shennan (2003), but I'm not sure if it's the same:

• Jordan, P., Shennan, S.J., 2003. Cultural transmission, language, and basketry traditions amongst the California Indians. Journal of Anthropological Archaeology 22, 42–74. https://doi.org/10.1016/S0278-4165(03)00004-7
