The compressed document format includes at the end of the document chunk
the indicies of the heads of the document. Older versions of the
javascript implementation do not include these indicies so we allow them
to be omitted when decoding.
Whilst we're here add some tracing::trace logs to make it easier to
understand where parsing is failing.
The latest clippy (90.1.65 for me) added a lint which checks for types
that implement `PartialEq` and could implement `Eq`
(`derive_partial_eq_without_eq`). Add a `derive(Eq)` in a bunch of
places to satisfy this lint.
Expose `automerge::AutoCommit::with_actor()` through `AMcreate()`.
Add notes to clarify the purpose of `AMfreeStack()`, `AMpop()`,
`AMpush()`, `AMpushCallback()`, and `AMresultStack`.

Now that all crates support the storage-v2 feature flag of the automerge

For some usecases the overhead of compressed columns in the document
format is not worth it. Add `Automerge::save_nocompress` to save without
compressing columns.

This is achieved by liberal use of feature flags. Main additions are:
* Build the OpSet more efficiently when loading from compressed
document storage using a DocObserver as implemented in
`automerge::op_tree::load`
* Reimplement the parsing login in the various types in
`automerge::sync`
There are numerous other small changes required to get the types to line
up.

It is useful to be able to generate a `serde::Value` representation of
an automerge document. We can do this without an intermediate type by
iterating over the keys of the document recursively. Add
`autoeserde::AutoSerde` to implement this.

Implement parsing the binary format using the new parser library and the
new encoding types. This is superior to the previous parsing
implementation in that invalid data should never cause panics and it
exposes and interface to construct an OpSet from a saved document much
more efficiently.

The representation of changes in storage-v2 is different to the existing
representation so add accessor methods to the fields of `Change` and
make all accesses go through them. This allows the change representation
in storage-v2 to be a drop-in.

The existing implementation of the columnar format elides a lot of error
handling (by converting `Err` to `None`) and doesn't allow writing to a
single chunk of memory when encoding. Implement a new set of encoding and
decoding primitives which handle errors more robustly and allow us to
use a single chunk of memory when reading and writing.

Op IDs in the OpSet are represented using an index into a set of actor
IDs. This is efficient but requires conversion when reading and
writing from storage (where the set of actors might be different from
ths in the OpSet). Add a trait for converting between different
representations of an OpID.

We have parsing needs which are slightly more complex than just reading
stuff from a buffer, but not complex enough to justify a dependency on a
parsing library. Implement a simple parser combinator library for use in
parsing the binary storage format.

The colunar storage format allows for values which we do not know the
type of. In order that we can handle these types in a forward compatible
way we add ScalarValue::Unknown.

The new storage implementation is sufficiently large a change that it
warrants a period of testing. To facilitate testing the new and old
implementations side by side we slightly abuse cargo's feature flags and
add a storage-v2 feature which enables the new storage and disables the
old storage.
Note that this commit doesn't use `--all-features` when building the
workspace in scripts/ci/build-test. This will be rectified in a later
commit once the storage-v2 feature is integrated into the other crates
in the workspace.
