use MY_PASSWORD in examples and vignettes

[jonathancallahan]

In order to have reproducible examples and vignettes, we should use specific time periods. In order to do this, we will have to use our WRCC password which cannot be seen in the code base.

My solution at the moment is to just have password = MY_PASSWORD in examples and vignettes and set that global variable manually before I Build > Check or pkgdown::build_site().

This task is to track down all the places that don't use our package internal example datasets and make sure they specify the password.
