What is the SQLite value binary format for workerd Durable Objects?

[Zino]

I am running a durable object locally like this:
wrangler dev src/index.ts --experimental-local --port 8701 --persist

I want to be able to read all of the storage for a durable object.

Workerd stores this in a SQLite file:

Allow Durable Objects to be stored persistently on local disk using SQLite

.wrangler/state/do/x.sqlite

The keys are strings, but the values are an unknown binary type.

What is the binary type so I can read the values whilst developing?

Question was answered here https://github.com/cloudflare/workerd/pull/302#issuecomment-1537177829 but as the answer says, that format is not guaranteed to stay the same.
