Context

The byte-to-integer conversion logic in the wiremessage and bsoncore packages is difficult to understand and maintain. It's also missing unit tests. Use the encoding/binary package instead, which has well-tested code and an API that documents the format(s) being used.

Definition of done

• Replace all manual byte-to-integer conversion logic in the wiremessage package with calls to encoding/binary functions.
• Replace all manual byte-to-integer conversion logic in the bsoncore package with calls to encoding/binary functions.
• Add unit tests for the wiremessage package.
