Belay

Bug Fixes
* On device `close`, we now issue 2 ctrl-c commands to make sure that any currently long-running command is canceled prior to issuing additional teardown commands.
* Fix some typing issues.

Bug Fixes
* Fix broken `Device.teardown()`. `teardown` was only broken when `()` was supplied. `Device.teardown` worked fine.
* Register `device.close` with `atexit`, so the teardown executers will be more robustly called.

Bug Fixes
* Fixes a bug where relative path dependencies specified in `pyproject.toml` were resolved relative to current working directory. Fixed to always be relative to project root.
* `belay run micropython` now respects `develop=true` sources.

Features
* Support for `develop` (editable) dependencies.

Misc Changes
* Convenience imports are now done prior to `__pre_autoinit__`.
* `belay update` output is a bit prettier.

New Features

Device
* New method `Device.sync_dependencies` to conveniently sync micropython dependencies bundled in a python package.
* Added new `Device.__pre_autoinit__` method hook. Intended for subclasses to invoke additional device setup like installing dependencies via `self.sync` or `self.sync_dependencies`.
* Added new `Device.__post_init__` method hook. Intended for subclasses to perform additional host-side initialization.

Package Manager
* Dependencies folder can now be configured via `dependencies_path` in `pyproject.toml`
* Support for multi-file dependencies. Can now efficiently handle git folders via a cache.
* New command `belay cache` for managing Belay's cache.
* `belay install` new option `--with` to include an optional dependency group.
* Optional groups are now fully supported.
* `belay --version` now prints the installed Belay's semver.
* Much improved docs.

Bug Fixes
* Fixed Circuitpython 8.0.0 incompatibility (fixes 93).
* Fixed broken convenience imports for boards with a reduced feature set (fixes 97).

Breaking Changes
* Exception `ConfigError` has been removed in favor of pydantic's `ValidationError`.

**Full Changelog**: https://github.com/BrianPugh/belay/compare/v0.16.2...v0.17.0

Bug Fixes
* Exit Raw REPL on device exit. This returns the micropython device to a more "normal" state that will (typically) play nicer with external programs, such as `rshell`. Fixes auxiliary issue in 78.
* Register `device.close()` with `atexit` so that device closes down properly even if not explicitly invoked.

Internal
* Increased process startup delay for Windows.
* Unregister process close after explicit close. Prevents (harmless) double process killing at end of integration tests.
