Progress: Continue program related work, updating fss_write.

Rename F_supported to F_supported and F_supported_not to F_support_not to avoid past tense.

Add a static empty range to make initialization assignment even easier.

For fss_write:
- Add most of the ignore range handling.
- Add support for the multiple Content per Object and handle errors for standards that do not support this.
- Lost of clean up and simplifications.
- Add a lot of fixme and todo comments for things not yet completed.

There is still a lot to do with fss_write.
The common write functionality is mostly done.
The standard specific functionality is not written for anything except FSS Payload.
