No possibility to control output WCS by regridding/rebinning exists in SODA.

This was possible in SIA1.0 for the spatial axis (only)
could be done by ADDing standard parameters to SODA for
Spatial resolution : SPATRES
Rotation : ROTA
Sky Projection : PROJ
or Alternatively by providing a WCS = (full text of WCS part of FITS header)

Skyview + CDS (SIA on top of Hips2FITS) have this functionality

Should we stabdardize it ?
And If yes should we extend it to SIA2 in virtual mode (SIA issue #8) ?
Or should we let it as a mixture of SIAP2 and SIAP1 parameters ?

Possibly solved by PR #12
