Implement Deref and DerefMut for In

makes it so the user doesn't have to add ".0" in most cases

LGTM. I do want to point out that you can also use a destructuring pattern as-is:

pub fn my_system(In(foo): In<Foo>) {
    // ...
}

99% that would be the case, but im working on a plugin with a type alias similar to:
type MyType = In<SmthPrivate>;
And I want the user to use MyType as a system param, etc.
in this case the user won't be able to deconstruct using In(x) = ..
