[Feature] Feeder improvements

[texx00]

The feeder requires a deep rework. As of now is a complete mess, too busy and to full of functionalities.
The complexity increased a lot everytime a functionality or a new compatibility issue was found.

• should create a "device type" class for Cartesian, scara, polar. These class should implement methods like: device ready, parse result, get path lenght, get element progress
• should divide the communication check from the feeder and use events with the device classes
• better buffer control (create separate class probably)
• overall cleanup

This has very high priority
