Allow to append a FAT16 partition image when building an ISO in hybrid mode.
This allows to add an extra writeable partition for when the ISO is burned to USB.
This feature is experimental and disabled by default.

The EFI partition for hybrid ISOs does not reliably show on all Windows systems, so we cannot use our "hack" of writing the configurations/PDFs to it. Reverted instead to a sane-sized EFI partition which is used just for booting. Added a note to the README that some tools such as Rufus support an ISO-mode to add a writeable partition at burning-time.

It is more convenient to not have to search for configuration files in different directories, and also helpful to see the standard configuration files, so move all ShredOS configurations into board/shredos.

Helps GRUB find the ShredOS volume when it otherwise cannot (such as when the IMG is used with Ventoy in BIOS)

To keep things consistent, copy the EFI configuration also to the EFI structure on the ISO9660 filesystem.

Improved the iso9660 argument order to better reflect modern best practices, inspired by the Debian distribution ISOs.

The entire iso9660 filesystem folder was restructured to replace partially unreadable legacy code with modern, readable and modular structures. Hardcoded paths were replaced with variables, as much as possible, to make the code work with different setups. A mode "both" was added, producing Debian-style hybrid ISOs for both BIOS and EFI usage, while still allowing for flashing to USB and/or burning to CD/DVD-ROM. The configuration GUI (via "make menuconfig") was also refactored and adapted to the new changes.
