Numato-gpio

-------------

This release adds a github workflow to deploy release packages on PyPI.

-------------

This version is released to relax the pyserial dependency in order to avoid
problems in the home-assistant project when the new pip resolver is in effect.
Additional features:

- Add a very basic unit-test against a pyserial mockup
- Configure tox to run the tests in a virtualenv
- Document CLI usage and improve CLI output

-------------

This release fixes an error in the cleanup implementation. When a device can't
be properly cleaned (e.g. because it's disconnected), its exception was not
handled, but fell through to the caller. So remaining devices could not be
cleaned up anymore.

- Fix crash during cleanup in case of a Serial communication failure

-------------

While this release is a thorough refactoring of most parts of the code, the
number of breaking changes has been kept to a minimum.

The following breaking change was made: Accessor functions in the NumatoUsbGpio
class namely id(), ver(), notify(), iomask() and iodir() are turned into
properties. Calls to these functions need to be changed to:

python
device_version = dev.id read access
dev.id = 5 write access, permanent change of the device ID

dev.notify = True turn on notifications
notifications = dev.notify read whether notifications are enabled or not


- Change accessor functions into properties (breaking change)
- Refactor out duplicated code
- Validate expected device responses instead of discarding read bytes
- Re-order methods by level of abstraction
- Add `clean` target to makefile, cleaning up package data from releases
- Add system tests for limited API tests against a connected real device

This release improves stability of the system by discovering devices from a
user defined list of device files. Instead of opening a whole generic range of
devices, the user can now select which ones to use. The default is still
/dev/ttyACM0 to /dev/ttyACM9 if no list is passed to the discover method.

- Support discovery from selected device files

This release removes the constraint to firmware version 9 of the Numato device.
Now all devices with the same command set and word-length might be supported.
Otherwise an error with a speaking message is raised.

- Check response of some commands during discovery/construction
- Remove strict check for firmware version 9
