Deserialize consensus objects using Read type
The BufReader wrapping is no longer needed after the rust-bitcoin
`0.32.4` release which contains the standardisation of the trait
bounds for deserialization to `Read` instead of `BufReader`.
What changed, and why it matters
This is a small cleanup change that removes an unnecessary BufReader wrapper when deserializing Bitcoin consensus objects. The underlying rust-bitcoin library now accepts a simpler 'Read' trait directly, so the code was updated to match. There is no security issue visible in the change.
No security action needed; this is a routine dependency-driven refactor.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch removes a BufReader::<_>::new(r) wrapper and passes the generic Read implementor r directly to consensus::encode::Decodable::consensus_decode. This is possible because rust-bitcoin 0.32.4 standardized deserialization trait bounds from BufReader to Read. The change is a refactor with no functional or security-relevant difference.
