Add xonsh support (#1375)

* Add basic xonsh support

* Add init xonsh command

* Add Xonsh install instructions in docs

* Add xonsh ctrl-R search

* update xonsh script and instructions

Summary of changes:
* Added duration to postcommand hook
* Switched main search operation to use `subproccess.run()` rather than running as an xonsh shell command - this a) allows us to capture stderr without needing a temporary file and b) avoids a weird broken-buffer state that results from running a fullscreen TUI and then programmatically editing the buffer
* Added support for immediately executing chosen command via `__atuin_accept__:` (like bash/zsh/fish)

* strip newline from command before sending to atuin

* Add basic xonsh support

* Add init xonsh command

* Add xonsh ctrl-R search

* Remove advanced-install guide (was accidentally re-added during rebase)

* Clean up

Xonsh doesn't import private functions into the local namespace when sourcing a file

* Add xonsh ro readme

* Respect ATUIN_NOBIND

* Format with black, and improve PEP8 compliance

* Add up search

* Format rust code
