More export options & formats for Gravit Designer (WEBP, AVIF etc)

Hello, please add the following export formats to Gravit Designer - as well as being a great vector editing program I also use it for bitmap image editing - so we need more formats to be available built-in.

• WEBP (for use on websites, smaller file sizes than PNG/JPG).

• AVIF (even better than WEBP).

• BMP (legacy - but still used today).

• GIF (obviously just for single-frame image exports - or introduce group-based frames to export animated GIFS).

• TIF (legacy - but still used today).

Also worth noting; please change the default export quality for JPG images to 100%.

Finally; please also add quick export icons for each new format you add.

If you are reading this please up-vote - thanks!
