Commitwise reviewable.

Effectively fixes #58, by allowing consumers (Synapse) to register a preserialisation callback for immutabledict.

Breaking change; will need a semver major bump. Consumers can add back support for frozendict by registering a preserialisation callback.

Synapse 1.62 started requiring semver-bounds on canonicaljson in matrix-org/synapse#13082, and I couldn't see anything else which imports canonicaljson on my machine. So only brand-new PyPI installations of Synapse 1.61 or earlier should be broken by this change. (Indeed, the point of that PR was exactly to allow us to make this kind of change.)

Looks like a good approach!

Thanks. I'll hold off from merging until I've tested this with Synapse.

A preserialisation hook allows you to encode objects which aren't encodable by the
standard library ``JSONEncoder``.

Did you want to update the version or changelog in this PR or will do it separate?

Was going to leave it---I think we usually make bumping the version number part of a release

I tested Synapse against this in matrix-org/synapse@266370c and matrix-org/synapse@03e63ab. This passed trial and sytest, see https://github.com/matrix-org/synapse/actions/runs/4419129723/jobs/7747311770 (The other failures are due to me using a git+https:// dependency rather than a pypi one.) So I'm doubly encouraged that this change works.
