Crate zmodem2 

ZMODEM file transfer protocol crate. zmodem2::State::receive and zmodem2::State::send provide a synchronous and sequential API for sending and receiving files with the ZMODEM protocol. Each step corresponds to a single ZMODEM frame transaction, and the state between the calls is kept in a zmodem2::State instance. The usage can be described in the high-level with the following flow:

1. Create zmodem2::State.
2. Call either state.send(...) or state.receive(...).
3. If the returned zmodem2::Stage is not yet zmodem2::Stage::FileEnd, go back to step 2.
