Added new award "DXCC SAT" that only counts satellite QSOs (QSOs with
satName field set). This adds a new "satellite_only" key to award
definitions that filters to only include satellite communications.
Award definition:
- ID: dxcc-sat
- Name: DXCC SAT
- Target: 100 DXCC entities
- Only satellite QSOs count
