`AnyBitPattern` is not implemented for arrays where the element is `AnyBitPattern`

[marc0246]

I know from reading past issues and PRs, that the way the trait tree looks now is because of historical reasons and chaning it is out of the question. But this brings a pretty big limitation with it: because AnyBitPattern has a blanket impl where T: Pod, this means an array [T; N] where T: AnyBitPattern is not AnyBitPattern. This in turn causes the derive macro not to work when a struct contains such a field. Is this something that you would consider fixing (the derive macro)? If so I would happily work on it.

Just ran into this with CheckedBitPattern too.

Same as above, happy to work on the workaround in the derive macro.
