…for the case that the input map is not normalized (fixes #1584).

Removed the optional extname argument from:
- GEbounds
- GEnergies
- GGti
- GNodeArray
- GCTAPointing
- GMWLObservation
- GMWLSpectrum

Integrate code (default extno and extver handling in GFilename).

The GFilename::default_extname() has been removed and remplaced by an enhanced GFilename::extname() method that either returns the extension name set in the filename, or if not set, the string that has been provided as argument.

The GFilename class handles the decomposition of the filename into the true filename and a FITS extension name.

The port can no longer be reused and the class how looks for the next free port on the system. This allows multiple Hubs to run in parallel.

gammalib::expand_env replaces ~ or ~user by the user's home directory, ~+ by the value of the PWD environment variable and ~- by the value of the OLDPWD variable. If the user or the PWD or OLDPWD variable are not found, no replacement is done.

… "Column separated values".

…l seem to be biased in the ellipse size.

…runcate ellipse at 3 sigma (#1561).

…ve radius that is consistent with the Gaussian normalization (#1561).

…semimajor and semiminor axis.

Before the limitation was 5 times that values and this led to convergence problems when fitting the model. Limiting the model to 2.5 times the larger axis seems to avoid the problem. Note that this is certainly not a perfect fix of the problem, but it helps to make the working model for now. Solves at least #1561.

Add a warning that the method should not be used during setup.

…d. This is needed to provide correct results for cubes that are larger than the ROI.

These methods allow saving a spatial diffuse cube into a FITS file or FITS object.
