mice doesn't handle complex variable names

[Ralayax]

Describe the bug
mice doesn't handle complex variable names (like variables with spaces or other strange characters)

To Reproduce

library(tidyverse)
library(mice)

mice::boys |>
  rename(`whooooo 151""1512` = tv) |>
  mutate(`this is a 'terrible varname....a` = 0) |> 
  mice::mice()

Expected behavior
Should do multiple imputations

Additional context
I will create a pull request adding backticks to variables inside the mice formulas to fix the issue
