Add partition manager (#286)

Implements #262.

Goal of this PR is to have a crate that enables a storage device to be
separated into partitions statically and checked. It achieves this by
providing a general partition framework, implement typical traits from
`embedded-storage-async` and `block-device-driver`, and have proc macros
generate partition map definitions.
