Convert HEIC to JPG in Go

The “High Efficiency Image File Format” or HEIF is an image format often used by Apple devices. Although called HEIF, the file types are often heic (presumably the ‘c’ stands for container?) They use a similar encoding method of video formats and are deemed better quality and lower file size than standard jpeg files. In our example, we’re trying to convert these heic files back into jpg files though - so we can use them elsewhere, display them or what ever we choose.
