Modernize & Improve Image Loading/Exporting Techinques

[ShaharMS]

The code in ImageTools for loading/saving images from/to files/URLs is pretty rough and old. Heres my plan to renew it, as well as improve the format conversion system overall:

• vision.format subdirectory which contains everything specific to format conversions
• vision.format.from:
  • FromBytes: Use different libraries/implementations to load from different image formats
  • FromFramework: Use different implementations to load from different graphics frameworks
• vision.format.to:
  • ToBytes: Use different libraries/implementations to export to different image formats
  • ToFramework: Use different implementations to export to different graphics frameworks
• Depracate saveToFile and loadFromFile in favor of different forms of- from/to File/Url/Bytes

And for the more complex stuff (some of these may not get resolved, depends on difficulty/time it takes):

• Subfolder inside vision.formats for home-made decoders/encoders
• Implement a JPEG decoder (optionally an encoder, altho one exists in format)
• Support for decoding/encoding WEBP
