To get rid of hardcoded zeta tauri, I use the yale bright star catalogue to look for bright stars in the FOV.
Tests show that Zeta Tauri is found for crab pointing positions.
I set the limit to a magnitude of 4.0 for the analysis, so for crab the behaviour is not changed.
This also contains two fixes for the HDUReader and a feature addition:
Addressing HDUs by index is now possible
HeaderLines are now correctly parsed if multiple slashes are present
