Binary support?

[cheako]

Some binary data cannot be represented in an &str, so functions that take &[u8] are necessary. Unless I misunderstand or am using the wrong tool.

Use case is programing Marvell ARMADA 3700 over serial port.

Looking at this I can't believe this does not panic when reading half of an unicode char?

thanks for reporting this. It looks like you are trying to come up with a pull request. Is this correct?
I have very limited time for this project. If you issue a PR and it passes the tests and examples I will merge it

Much more testing is needed, but thanks for doing what you can to maintain this.
