GRAVITY+ support

[bourgesl]

• Validate new ASPRO2 config:
  • GPAO NGS VIS
  • GPAO NGS IR (same CIAO)
  • GRAVITY 'FAINT' (=G+): low vibration ~ 100nm, higher throughtput x 1.25, no laser noise
  • what atmospheric conditions for turbulence layer (h0) ?
• Improve ASPRO2 target handling:
  • hide AO/FT by default in main target list
• add new selectors for AO / FT targets in uv coverage panel to test AO/FT/SCI combinations
• improve ASPRO2 integration with SearchFTT
  • add link to SearchFTT
  • improved data retrieval and simbad update (+ fix duplicated names but different IDs)
• Update documentation on GRAVITY FT & new AO for GPAO NGS... (add references to gravity+ & gpao simulators)
  • generate Strehl chart vs aoMag for all vlti/chara instruments x ao

Later:

• Improve ASPRO2 target handling:
  • only show ancillary targets below science target (fix display order in observability plot)
• Do not ask the user (but do it silently) to update target with Simbad if is negative (or through another mecanism)
• better target selection handling by ID not name to better handle duplicated names or item selection (shared calibrators, AO or FT targets)
• SearchFTT: handle HMS/DMS coordinates properly in generated asprox files (HA = hours not degrees => div 15)
