MIME type

I would like to be able to create ImageFormat from a MIME type.

My specific use case for this functionality is decoding an image that comes from a js function.

if this feature is accepted, i will do a pr for it.

Draft

impl ImageFormat {
    fn from_mime_type(mime_type: &str) -> Option<Self> {
        match mime_type {
             "image/png" => Some(ImageFormat::Png)
             _ => todo!();
        }
    }
}
