v1.2 Added Stream Analyzer and new Provider Configs

[valentinfrlch]

Changelog

Features

• stream_analyzer takes a list of camera entities and analyzes the live camera feeds.
  This means you no longer need to record a video first and then call the video_analyzer, which is slower as it is executed sequentially and
  involves I/O operations. (video_analyzer is still available)
• The way the configuration is stored has been completely rewritten. It is now possible to have multiple configurations per provider. A restart is also no longer needed to remove an provider.

Bug fixes & Other small improvements

• The action call UI has been updated with better descriptions and examples.
• Config entries are now correctly unloaded when removing them, a restart is no longer necessary.
• Default values have been updated to provider better results
