Should a theme_bcmaps() go in the envreportutils package with other ggplot2 plotting themes?

I think that this might be a useful package for this purpose: https://cran.r-project.org/web/packages/ggsn/index.html

@stephhazlitt You may be right. My thought is that once geom_sf becomes available CRAN, bcmaps might actually import ggplot2 so then a user could grab data and plot all within the bcmaps package.

This issue could perhaps be morphed into a mapping utility along these lines:

Something we might include is that ggplot2 now includes the ability to set colour and fill scales via options. This could be useful for brand: https://ggplot2.tidyverse.org/reference/scale_colour_continuous.html

Some inspiration might be here: https://github.com/Nowosad/rspatial-map-challenge-2020

This is also pretty pretty, imo https://twitter.com/katiejolly6/status/1336027945773617152. However maybe more of a figure?

I'm starting to like and use tmap more and more, it would be good to at least include it, if not focus on it

I think this is very related to #43 and if we implemented that, could really move towards some nice looking maps (using tmap).
