gganimate 1.0.9.9000

Fix for using "svg" device during knitting (#484)
Fix for correctly getting chunk options during knitting (#485)
Fix a bug in transition_reveal() that would remove data during transitions (#480 and #473)
General upkeep to keep it in line with the evolvling coding principles in ggplot2 (move to using vctrs, cli, lifecycle, etc)
transition_reveal() now throws an error when it is used in conjunction with stat_align() and transitioning before the stat has been calculated (#476)
Label interpolation now works when labels are expressions (#439)
as_html_video() gains muted, loop, and controls argument to control presentation of the video. Like autoplay these can be controlled during knitr through the chunk options (e.g. gganimate = list(muted = TRUE, loop = TRUE)) (#444)
Make the build process up-to-date with ggplot2 3.5.0

Fix a bug when creating labels from aesthetics that include glue expressions (#422)
Fix a bug in ffmpeg detection (#346, @rfaelens, #360, @adamdsmith)
Remove plyr dependency
Fix a bug in transition_filter() in the presence of NA filter values (#404, @rsaporta)
Fix a bug with static layers that include position adjustments (#418)
Fix a bug in transition_time() where multiple time values in the same frame would lead to unexpected stacking of the data (#414)
Fix a bug in transition_reveal() where coinciding tweens would result in wrong direction of the arrow (#409)
Fix a bug in transition_layer() when the last layer had an exit duration (#384)
Fix a bug in transition_time() when facets had data with different starting time (#357)
Make sure exclude_layer in view_*() is taken into account
Fix a bug when using a view with coord_flip() which would result in weird flickering and movement of the position guies (#336)
Fix a bug in transition_reveal() that would require input to be ordered along the time dimension for point-like geoms (#323)
Fix a bug in view_follow() that would result in errors when used with discrete scales (#304)
Fix bug in transition_states() where too few frames relative to states in combination with wrap = FALSE would cause an error (#301)
Fix a bug in transition_time() when the time dimension contained NA values (#307)

Fix a bug in ffmpeg_renderer() where the fps argument were being ignored.
Make sure ggraph objects registers the graph context after they are promoted to gganim objects.
Better fallback strategy for lack of gifski.

Fix a conditional in the plot building step to make it work with the ggplot2 3.1.1 hotfix.

Fix bug in transitions when the group aesthetic was late evalued (#262)
Better fade support for geom_smooth(). Both ribbon and line will now fade.
Fix bug in transitions when group aesthetic was a string that could be interpreted as a double (#266)
Fix bug in shadow_mark() where future shadows were drawn above the main frame data.
Better error messages when a layer type is not supported by the transition
Fix bug where transitions didn't work with difftime/hms for specifying durations when transition variable was a POSIX or date class.
Fix bug where using a view would modify the plot coordinate system in-place, resulting in modifications to the original plot object.
view_follow now works with transformed scales.

First CRAN release, featuring a complete rewrite... Too much stuff to put in a changelog
