postcard-schema: inconsistent schema names for [T] and [T; N]

[max-heller]

Is there a reason for [T]'s schema name to be &[T] while [T; N]'s is [T; N] (no &)? It seems like it'd be more consistent to remove the &.

	impl<T: Schema> Schema for [T] {
	const SCHEMA: &'static NamedType = &NamedType {
	name: "&[T]",
	ty: &DataModelType::Seq(T::SCHEMA),
	};
	}
	impl<T: Schema, const N: usize> Schema for [T; N] {
	const SCHEMA: &'static NamedType = &NamedType {
	name: "[T; N]",
	ty: &DataModelType::Tuple(&[T::SCHEMA; N]),
	};
	}

I think that's reasonable. The idea was to make it clear the former is a slice (e.g. with a len), whereas the latter is an array. I don't often use bare unsized slices, so I used &[T] out of habit.

That being said, [T] is probably more consistent.
