genio (cargo): A type safe, low level replacement for `std::io`.  Supports `no_std` for embedded development, just disable cargo feature `std`.  Because of limitations of `std::io::Error` type, `genio` provides `Read` and `Write` traits that allow implementors to choose their own type. This type can be better at expressing what kinds of error can happen.
