[pbs-devel] [PATCH pxar] decoder: sync: remove needless wrapper around `decoder::Contents`

[Max Carrara]

Similarly to the `impl` for `tokio::io::AsyncRead` in `decoder::aio`,
this implements the `std::io::Read` trait on `decoder::Contents`
directly while removing the wrapper.

This allows `decoder::Contents` to be used in both synchronous
and asynchronous contexts.
