More work on Energy consumption

• Heavily reworked the energy consumption part of the integration, you are now able to import your statistics directly from Tuya's cloud (goes back and fetches the last 5 years of stats)
  
• Fixes on the API connection logic (should fix some random bugs)
  
• All changes from the beta are also present in this version
  
  Please read the doc here if you want to import your statistics
  
  Enjoy!
