add support for binary format in tuple data

[imor]

This PR adds support for parsing a TupleData in binary format as defined in the docs. This is useful for the case when the START_REPLICATION command contains the binary option for pgoutput plugin defined on this docs page.

@petrosagg could you please take a look at this PR. It adds support for binary format in TupleData. Also has the postgres-replication crate been published to crates.io? Can a new version be published after merging this PR?

[petrosagg]

@imor thanks a lot for this PR, the change looks great! Somehow it slipped past my attention.

Unfortunately postgres-replication can't be published in crates.io for now because it depends on a git dependency of the forked tokio-postgres crate. There is a long-standing upstream PR in rust-postgres that would enable that but it's been open for many years now

Ah ok, no worries. Thanks for merging.
