Derive Macro bevy_enum_filter_derive::EnumFilter

#[derive(EnumFilter)]

Derive the EnumFilter trait on the given enum.

This will do a couple things:

1. It will, of course, implement the EnumFilter trait
2. It will generate a module with filter components for each enum variant

The generated module will have the name of the enum (snake-cased), appended by _filters. So the enum, MyEnum, would generate a module called my_enum_filters.

The module will contain a zero-sized marker component struct for each variant. For example, given the following enum:

enum Foo {
  Bar,
  Baz(i32),
}

We would end up generating the module foo_filters which contains the markers Bar and Baz.

See the Enum! macro for how to properly use this generated module.
