Variable star size

[Kroc]

Via Elite-B; provide visible variation on the size of stars.

This yields a number of other related behaviours, such as:

• Fuel scooping from stars varies by star size and type; larger stars yield better scooping but a safer distance is required
• Planets are farther from bigger stars and closer to smaller stars
• Where you drop into a system is dependant on the size of the star; larger stars have greater gravity and hyperspace will drop you off closer to them. Smaller stars will drop you off nearer the planet
• Smaller ships are likely to overheat if they pursue you around the star too much
• Thargoids cannot release Tharglets near the sun (they overheat quickly)

The galactic chart extracts a Z value for stars! We can use this to determine star-sizes in an OG-compatible manner
