What problem does this solve or what need does it fill?

Currently I use the storage binding to pass a vector of elements to a shader. Storage should be supported on the new AsBindGroup derive, otherwise it isn't really a replacement.

What solution would you like?

Support writing#[storage(0)] the same way #[uniform(0)] is supported.

What alternative(s) have you considered?

None, this is a pretty small change that fits in to the rest of the AsBindGroup macro, just seems like a strange missing piece.
