Description

It would be helpful to have a fixed size BArray type which is just a [u8; N]. This is especially useful when reading bytes directly into packed structs (i.e. with bytemuck) instead of having to use an array.

If there is no overall rejection of such an addition I can work on a pr.

Contributor guide

Research direction
Study the existing BString and Bytes types in bstr to understand the pattern for creating a fixed size array type. Look into implementing [u8; N] wrapper with bytemuck compatibility.
