peek suggests no side-effects, but this does in fact remove the entry from the queue.

Also, update the docs to note that wait does a submit.

CHANGES:

New features:

- Add `Uring.timeout` (@bikallem ocaml-multicore/ocaml-uring#59).

- Add `Uring.read` and `Uring.write` (@haesbaert ocaml-multicore/ocaml-uring#62).
  These are simple wrappers for read(2) and write(2).

- Add `Uring.unlink` (@talex5 ocaml-multicore/ocaml-uring#65).
  This uses unlinkat(2), and so can also be used to remove directories.

- Add support for uring probes (@talex5 ocaml-multicore/ocaml-uring#70).
  Allows checking whether a feature is supported by the kernel at runtime.

- Rename `peek` to `get_cqe_nonblocking` (@talex5 ocaml-multicore/ocaml-uring#67).
  The old name was confusing because it does remove the item from the ring.

- Update to liburing 2.2 (@talex5 ocaml-multicore/ocaml-uring#56).

- Add `Uring.active_ops` (@talex5 ocaml-multicore/ocaml-uring#68).
  Avoids needing to track the value returned by `submit`, which is important as it is sometimes called automatically.

- Add `Uring.iov_max` constant (@talex5 ocaml-multicore/ocaml-uring#76).

- Add `Uring.get_debug_stats` (@talex5 ocaml-multicore/ocaml-uring#64).
  This should make it easier to check that the uring is behaving as expected.

Performance:

- Introduce a Sketch buffer per Uring (@haesbaert ocaml-multicore/ocaml-uring#63).
  The main motivation of this change is to avoid having one malloc per packet in readv(2), writev(2) and friends.

- Use `submit_and_wait` where appropriate (@haesbaert ocaml-multicore/ocaml-uring#69).

- Add a `readv` benchmark (@talex5 ocaml-multicore/ocaml-uring#64).

- Avoid unnecessary use of `CAMLparam` in the C stubs (@haesbaert ocaml-multicore/ocaml-uring#61).

Bug fixes:

- Prevent ring from being used after exit (@talex5 ocaml-multicore/ocaml-uring#78).

Build changes:

- Remove use of notty for formatting benchmark results (@talex5 ocaml-multicore/ocaml-uring#71).
  It prevented uring from being tested on OCaml 5.

- Use MDX for README (@talex5 ocaml-multicore/ocaml-uring#57).

- Convert tests to MDX (@talex5 ocaml-multicore/ocaml-uring#58 ocaml-multicore/ocaml-uring#73).

- Use opam-repository syntax for license (@kit-ty-kate ocaml-multicore/ocaml-uring#72).

- Remove internal `is_dirty` flag (@talex5 ocaml-multicore/ocaml-uring#77).
