+ Built in coder that supports PNG, JPEG, TIFF, includes support for progressive decoding.
+ 
+ GIF
  Also supports static GIF (meaning will only handle the 1st frame).
  For a full GIF support, we recommend `FLAnimatedImage` or our less performant `SDWebImageGIFCoder`
+ 
+ HEIC
+ This coder also supports HEIC format because ImageIO supports it natively. But it depends on the system capabilities, so it won't work on all devices.
+ Hardware works if:  (iOS 11 || macOS 10.13) && (isMac || isIPhoneAndA10FusionChipAbove) && (!Simulator)
