icons - specifies an array of objects representing image files that can serve as application icons for different contexts.
Object members are
# sizes - A string containing space-separated image dimensions.
# src - The path to the image file. If src is a relative URL, the base URL will be the URL of the manifest.
# type - A hint as to the media type of the image. The purpose of this member is to allow a user agent to quickly ignore images with media types it does not support.
# purpose - Defines the purpose of the image, for example if the image is intended to serve some special purpose in the context of the host OS (i.e., for better integration).
Valid values are
"badge": A user agent can present this icon where space constraints and/or color requirements differ from those of the application icon.
"maskable": The image is designed with icon masks and safe zone in mind, such that any part of the image outside the safe zone can safely be ignored and masked away by the user agent.
"any": (Default) The user agent is free to display the icon in any context.
