reedline 0.12.0

A readline-like crate for CLI text input
Documentation
# Contributing

reedline's development is primarily driven by the [nushell project](https://github.com/nushell) at the moment to provide its interactive REPL.
Our goal is to explore options for a pleasant interaction with a shell and programming language.
While the maintainers might currently prioritize working on features for nushell, we are open to ideas and contributions by people and projects interested in using reedline for other projects.
Feel free to open an [issue](https://github.com/nushell/reedline/issues/new/choose) or chat with us on the [nushell discord](https://discordapp.com/invite/NtAbbGn) in the dedicated `#reedline` channel
