The pool was prone to deadlocks, especially due to having a single pool
for rx+tx. If the pool got full with rx'd packets it would deadlock because
processing a rx packet requires doing another allocation on the pool, for
the possibly tx'd response, before deallocating the rx'd packet.
This also allows Device impls to allocate the packet memory in a particular
RAM kind, if needed for example to do DMA.
The `Device` trait is now token-based, like smoltcp's. In the end, this
is better because it allows callers to manage memory however they want (including
with a pool if they want to).
The "must not be called reentrantly" invariant is too "global" to
maintain comfortably, and the cost of the RefCell is negligible,
so this was a case of premature optimization.

It currently contains whoever was first to write some code for the crate,
even if many more people have contributed to it later.
The field is "sort of" deprecated, it was made optional recently:
https://rust-lang.github.io/rfcs/3052-optional-authors-field.html
Due the the reasons listed there I believe removing it is better than
setting it to generic fluff like "The Embassy contributors".
461: nrf: add initial nrf5340 support r=Dirbaio a=Dirbaio
Thanks to `@diondokter's` work on DPPI this was quite easy! :)
