Actual behavior

When using mix phx.gen.live to generate a schema it is not possible to have array of enums. Example below:

mix phx.gen.live Tests Testy testy numbers:array:enum:one:two:three                 
** (Mix) Unknown type `numbers:enum:one:two:three` given to generator

This is the full output, printed out by this function.

Expected behavior

I'd like to see the correct schema being generated, the field should look like:

    field :numbers, {:array, Ecto.Enum}, values: :one, :two, :three

but I understand that it's not easy generating code, even the current implementation is magical and does not take much adaptation to go from array:string to enums, thanks.
