parse_supported_security_types returns nom::Err::Incomplete(nom::Needed::Size(2)) if we give it a one byte input (whose value is 2)
when parse_server_security_type returns nom::Err::Incomplete(nom::Needed::Size(4)) if we give it a one byte input

In the first case we need two additional bytes to the first byte
In the second case, we need a total of 4 bytes, including the first one we got

Rust nom doesn't give you a usable number especially when their is a chain of parsers

No backport as it is a new feature
