feat: add `dob` sub-package for spore-sdk

[ashuralyk]

Description

since we created DOB/0 protocol, this protocol requires developer write RUST code to generate its pattern for deploying Cluster, so we plan to write a codec procedure for DOB/0 right in spore-sdk, as it's written in TypeScript which is more familiar for the most of programmers in our eco-system.

just ignore the failure of CI workflow, it caused by the conflict of cross and cargo version, which emits errors while compiling spore-contracts
