Add binary dtype to Series.in/2

[Jhonatannunessilva]

This PR allows the Series.in/2 function to receive series with binary dtype.

Addition to: #420 and #475

Before this PR, if you try to compare two binary series using the Series.in/2 function, an error will be returned:

iex(1)> s1 = Explorer.Series.from_list([<<239, 191, 19>>, <<2>>, <<3>>], dtype: :binary)
#Explorer.Series<
  Polars[3]
  binary [<<239, 191, 19>>, <<2>>, <<3>>]
>

iex(2)> s2 = Explorer.Series.from_list([<<239, 191, 19>>, <<0>>, <<3>>], dtype: :binary)
#Explorer.Series<
  Polars[3]
  binary [<<239, 191, 19>>, <<0>>, <<3>>]
>

iex(3)> Explorer.Series.in(s1, s2)
** (ErlangError) Erlang error: :nif_panicked

    (explorer 0.6.0-dev) lib/explorer/polars_backend/shared.ex:23: Explorer.PolarsBackend.Shared.apply_series/3

After this PR the result is:

iex(3)> Explorer.Series.in(s1, s2)                                                      
#Explorer.Series<
  Polars[3]
  boolean [true, false, true]
>
