Integrate `miden-objects`

[igamigo]

miden-objects was created in the protocol repo recently. It's also being integrated in the node (0xMiden/node#2551). We'll eventually need to make use of this crate and these structures.

Some things to keep in mind in regards to implementation:

• Protocol config: complete ProtocolConfigs by commitment. Bundle known networks; require custom networks to provide one explicitly. See Support ProtocolConfig (v0.17) node#2546.
• We could probably remove a lot of the de/serialization code that this repo hosts.
• There are also some streaming endpoints that are being added.
• Not sure if the winterfell serde is getting removed, but then the binary format we keep in the Store will need to change.
