Read/Write traits for reading common formats like length-prefixed packets.
`rwutils` handles a few common formats of binary data:
* C-style strings, that is 0-terminated sequences of non-zero bytes inside
the `bytes0` module. Check its docs for examples of reading Strings.
* Length prefixed packets, a u8/u16/u32/u64 of the number of bytes to
read, followed by the actual data. See `length_prefix`.
All readers are implemented as additional traits for the `io::Read` and
`io::Write`. After using them, additional methods become available on these
types.
**Please read the notes regarding security** in module as well,
especially if you are handling untrusted user input.
