v0.2.2 Changes

This release should be more stable than other recent updates.
I've finished doing major refactoring/restructuring to the codebase and new bugs should hopefully be fixed in this release.

General

• Fixed bug introduced in v0.2.1 breaking cloud print services
• Fixed bug in config flow during re-configure of authentication
• Fix long standing bug during config flow where errors are not reported to frontend during printer selection showing an empty list.
• Fixes for some unhandled MQTT data updates
• Add job_download_progress attribute to Current Status sensor
• Add supports_mqtt_login attribute to MQTT Connection Active Binary Sensor
• Add reason project data as print_status_message to Job Name sensor attributes

Frontend only

• Major refactor throughout for strict typechecking, linting + render optimisations
• Disable file manager in frontend for web based authentication

Library only

• Refactored exceptions and error strings throughout
• Slotted all classes for memory improvements
• Refactored into more organised folder structure
