More support for `forcats`

[etiennebacher]

What functionality are you missing? https://forcats.tidyverse.org/reference/index.html

Is this functionality present in the tidyverse or in polars (or both)? tidyverse

• fct_relevel()
• fct_inorder()
• fct_reorder()
• fct_rev()
• fct_collapse()
• fct_lump()
  • fct_other()

are the ones I frequently use. Of note, rev() from base is not available. I would recommend dropping fct_rev() and support rev() useful in more conditions.

[etiennebacher]

Thanks, rev() is now supported on the github version

I think this mostly lacks support in rust-polars for now (e.g https://github.com/pola-rs/polars/issues/7981) and I don't know if there are plans to develop this upstream
