Control regex matching behavior

Dependency-free drop-in alternative for stringr::regex().

regex(
  pattern,
  ignore_case = FALSE,
  multiline = FALSE,
  comments = FALSE,
  dotall = FALSE
)

`pattern`	Pattern to modify behavior.
`ignore_case`	Should case differences be ignored in the match?
`multiline`	If `TRUE`, `$` and `^` match the beginning and end of each line. If `FALSE`, the default, only match the start and end of the input.
`comments`	If `TRUE`, white space and comments beginning with `⁠#⁠` are ignored. Escape literal spaces with `⁠\\⁠`.
`dotall`	If `TRUE`, `.` will also match line terminators.
