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)
