fix: load cdf latest version

[ion-elgreco]

Description

The eq check was incorrect, should be only greater than.

Also found small bug in get_latest_version. It would return a version that might be invalid if the start version is not existent. Add a robustness check in there and one recursion loop, to start from -1. This will either result in the correct version or stay -1 an throw not a table location :)
