Being

Fixed
- Unnecessary PCAN patch causes errors on Darwin

Fixed
- Missing templates package data

Added
- Notify user that Being is running when invoking `awake()`
- `AudioBackend` and `Mic` block for audio onset detection.
- Stop ongoing homing when pressing homing button again
- Finalizing documentation
- `audio` and `rpi` extra requirements

Changed
- `DummySensor` now resides in `being.sensors` module.
- Changed being config file to YAML
- *Alphabetical* instead of *most recently modified* order for motion curves
- Max height for behavior and editor widget
- Deactivate power and homing button when there are no motors
- Resize editor when new content messages arrive
- Only display widgets when the corresponding blocks exist

Removed
- Relay connectables

Fixed
- Installation issue. `patch_pcan_on_darwin()` only when can & canopen are installed.

Changed
- Default PDO mapping: `TARGET_POSITION` and `TARGET_VELOCITY` both over PDO 2.
- `Current Actual Value` via PDO instead of SDO.
- Controller now tries to restore node's state after homing.

Removed
- Homing's capture, restore and teardown methods.
- Replaced `switch_off_drives` method `CanBackend` with `turn_off_motors` method (which disables drives with a timeout).

Fixed
- `CrudeHoming` with timeout during homing

Fixed

- Bugfix for `named_tuple_from_dict`. With Python 3.7 named tuples without default values have no `_field_defaults` attribute.

Fixed

- Unselected / wrong knots got deleted because Array.sort() defaults to lexicographic order for numbers. See [further resources](https://javascriptwtf.com/wtf/numbers-sorted-alphabetically).
