Parameters in save_fits function

[bschneider-astro]

Hi @cylammarco, regarding the output parameter of the save_fits function, it would be interesting to have the possibility to save the resampled wavelength array corresponding to flux_resampled. I assume this information is available in the header but I think it would be nice to have an HDU with the values directly. Also, in the case of a 1D spectrum it might be interesting to save the data in an HDU table rather than HDU images, with each column of the table corresponding to flux, wavelength, flux_err and sky.

Hi @bschneider-astro, if having a wavelength_resampled HDU would make life easier I can certainly add that as an option in v0.5, which is something I will start working on very soon.

Regarding HDU image and HDU table. An image type was chosen because in that way the output 1D spectrum can be read by iraf's splot. This is a minimal iraf-compatibility I am providing. Do you know much about other spectral analysis toolkits? Do they usually read both HDU image and HDU table?
