ggsci 3.1.0

New features

The BMJ color palettes are implemented in scale_color_bmj() and scale_fill_bmj() (thanks, @huichen99, #32).

Convert Rd syntax to Markdown in roxygen2 documentation. This simplifies documentation formatting and makes it much easier to add new color scales for contributors (#35).

Detect ggplot2 version at runtime to determine if the argument scale_name is needed for all discrete_scale() calls. This ensures ggsci always works regardless of the ggplot2 version installed (thanks, @flyingicedragon, #29).

Remove scale_name from all discrete_scale() calls because the argument has been deprecated in ggplot2 3.5.0 (thanks, @DanChaltiel, #25).

Expand the FAQ vignette to include a solution for customizing color selection and ordering in a palette with self-defined color scale functions (#23).
Fix “lost braces” check notes on r-devel by using Unicode characters (a91faf1).

Added three Flat UI color palettes in
- scale_color_flatui()
- scale_fill_flatui()
and one color palette inspired by the logo of frontiers.org in
- scale_color_frontiers()
- scale_fill_frontiers() (thanks, @clarajegousse, #14).
Added three COSMIC color palettes in
- scale_color_cosmic()
- scale_fill_cosmic()
(thanks, @jhrcook, #5, #7).

Use a proper, three-component version number following Semantic Versioning.
Reduce output figure size in vignettes and README.Rmd by switching to the ragg PNG device and using pngquant for compression.
Added a new vignette on frequently asked questions.
- A simple solution to interpolate the color palettes when the data has more categories than the number of colors in a discrete color scale.
- A note on using a color scale consistently for multiple ggplot2 plots by setting global options (thanks, @DanChaltiel, #13).
Replace size with linewidth in code examples for ggplot2 >= 3.4.0.
Replaced the previous logo with a new hex sticker logo.
Replaced previous CI/CD solutions with GitHub Actions workflows.
Fixed broken or moved links in function documentation and vignettes.
Removed the LazyData field from DESCRIPTION.

Use system font stack instead of Google Fonts in vignettes to avoid pandoc SSL issue.
