highdir 0.6.0

• Add hd_reset_theme() function (#21)
• Add venn diagram with gg_venn or hc_venn backends.
• New feature added to support for

hd(mode = "dynamic")
hd(mode = "static")

dynamic replaces the previous highcharter backend and static replaces the previous ggplot2 backend.

Breaking changes

• Introduced a new mode argument with values "dynamic" and "static" to replace backend-specific values.
• The backend argument indna hd() and related functions is now deprecated and will be removed in a future release.
• Existing code using:

hd(backend = "highcharter")
hd(backend = "ggplot2")

continues to work but produces a deprecation warning.
