.data$ has been deprecated for some dplyr functions

[dblodgett-usgs]

For some reason, dplyr::select, dplyr::rename, and tidyr::unnest now throw deprecation warnings for the .data$attribute rather than using bare variables. I'm really not clear on all the nuances behind tidyselect but these only need to be changed for select and rename -- arrange, filter, group_by, etc. do not work with the change to surrounding the attribute name in "attribute"

https://community.rstudio.com/t/use-of-data-in-tidyselect-expressions-is-now-deprecated/150092 talks about it a bit and this issue is where it was implemented: r-lib/tidyselect#169

Seems silly, but I guess I'll go through an change all the instances of this to avoid all the warnings that are going to start cropping up for users.

https://dplyr.tidyverse.org/articles/programming.html now describes this situation better -- it appears to have been redeployed in the last few days.
