[Book8088] Support for XT-IDE F8 BOOT ROM feature (adding an option rom to use with it)

[Yrouel]

I discovered someone compressed IBM BASIC C1.10 to fit in a 32k ROM:

I also discovered it boots just fine in the Book8088 by simply concatenating it inside the ROM just after XT-IDE, however while it does boot it only boots that, XT-IDE doesn't load.

EDIT: It seems to be an issue with that specific ROM so I don't know if it could be supported, this version should work but I don't know how to or even if it could be fitted in the Book8088 ROM

On the other end I'd like for the Book8088 to boot into basic when no CF-Card is inserter or manually by using the F8 BOOT ROM feature of XT-IDE.

I understand you most likely cannot just distribute that file, however would it be possible to add support for this scenario (and eventually any other generic option rom) and possibly a flag on the Make file to build with that extra binary to be provided by the user?
