Description

Right now the crate does not expose a way to construct a Block https://docs.rs/subxt/latest/subxt/blocks/struct.Block.html
You need to fetch it from a source chain, which is not ideal for simple unit tests.

It would be great to expose a constructor for test target.

Research direction

Start with the documented subxt::Block type at the linked docs.rs page and trace how blocks are currently obtained from a source chain. Determine the smallest public construction API that supports unit tests. Done means callers can construct a Block without fetching it from a chain, with appropriate unit-test coverage.
