biscale 0.2.0

• Add sf as a required instead of a suggested dependency. This resolves issues that appeared with newer releases of the tibble packages.
• Drop support for R 3.3 because CI tests now fail on this release. Minimum release of R is now 3.4.
• Add bi_scale_color() as a compliment to existing functionality. This adds the ability to create bivariate point and line maps as well.
• Add bi_pal_custom() to support custom palettes.
• Additional confirmatory CI testing for R 3.4 added to Linux (now the xenial distribution), macOS, and Windows.

• Add non-standard evaluation to bi_legend()
• Fix typos in README.Rmd, index.Rmd, and in bi_class.R
