[Proposal] Path.wildcard with [:case_insensitive] option

[Charles Okwuagwu]

Hi, 

I feel this could be a useful addition to the `Path.wildcard/2` function.

How to do case-insensitive search might not be immediately obvious, but it does have some value.

Would a PR for this be welcome?

(https://stackoverflow.com/a/45597449/44080)

defmodule A do
  def case_insensitive_glob(glob) do
    Regex.replace(~r/[a-zA-Z]/, glob, fn letter ->
      "[#{String.downcase(letter)}#{String.upcase(letter)}]"
    end)
  end
end

glob = A.case_insensitive_glob("**/*reAdmE.*") |> IO.inspect
Path.wildcard(glob) |> IO.inspect

FWIW, this might have value on *nixes but not on Windows. Windows is case-insensitive in regards to paths.

Path.wildcard is case-sensitive regardless of platform.

This would be useful on any platform.

My mistake for making the assumption that the behavior would correspond to the behavior of the underlying OS.
