Create a bootable optical disk image (e.g. for ventoy)

[stapelberg]

https://www.ventoy.net/ seems pretty cool, but only works with ISO images, not disk images.

distri currently only offers disk images. Maybe we should try to generate an ISO image.

Maybe these resources help:

• https://wiki.debian.org/RepackBootableISO
• https://wiki.debian.org/ManipulatingISOs

Ventoy is indeed pretty cool and they have started supporting IMG files. Per my request, @ventoy added support for Lakka and LibreELEC images.

Not sure if there are other use cases for ISOs or if it make sense to just request support for distri IMGs.
