Vortex Buffer

For now, a Vortex buffer is implemented as a very thin wrapper around the Tokio bytes crate. In the future, we may re-implement this ourselves to have more control over alignment (see https://github.com/tokio-rs/bytes/issues/437)

lib.rs:

A byte buffer implementation for Vortex.

Vortex arrays hold data in a set of buffers.

Alignment

See: <https://github.com/spiraldb/vortex/issues/115>

We do not currently enforce any alignment guarantees on the buffer.
