This package contains an implementation of SLIP for message encapsulation on a serial line. It works with toit's port library package
The protocol works with delimiting all messages with an escape sequence 0xC0
If a 0xC0 appears in data, it is replaced by 0xDB 0xDC. 0xDB in the stream in turn will be replaced by 0xDB 0xDD
The esp serial flasher protocol uses this transport mechanism
