Updated for Patch 2.4.1

Adjusted Avorion version dependency to not break at newer patch updates

Adjusted weight of sectors as those were way to rare

additional smaller asteroids spawned alongside bigger asteroids, have the same resource probability if inside resource rich sector.

This update changed how the different variants are generated.

There are 5 new Sector types to be generated:
- Normal rich asteroid sector
- Big asteroid sector
- Big rich asteroid sector
- Huge asteroid sector
- Huge rich asteroid sector

The chances of those sectors to be generated were adjusted:
- Normal rich asteroid: 25% of normal asteroid sectors
- Big asteroid sector: 4x times rarer than normal asteroid sectors
- Big rich asteroid sector: 30% of all big asteroid sectors
- Huge asteroid sector: 20x time rarer than normal asteroid sectors
- Huge rich asteroid sector: 45% of all huge asteroid sectors

The long loading time for new sectors is fixed!
