feat(balance): Reduced the Heavy Rocket's damage while increasing its…

… blast radius (endless-sky#9912)

Reduces the damage dealt by heavy rockets from 1060/900 to 790/670, and increase their blast radius from 50 to 90. This is a drop of about 25% to damage, and an increase of 80% to blast radius.

The description of heavy rockets notes that they're primarily effective against groups of fighters, and this change leans further into that, making them more clearly distinct from the Torpedo, the premier anti-HW weapon for small ships.

"If a ship has turrets, your Sparrow can't get close enough to hit it with your guns without being damaged, and then it's just a matter of whose weapons and shields are stronger. And one Heavy Rocket hit could nearly disable you. Also, if it has anti-missile turrets, you can't count on hanging back and bombarding it with missiles from long distances, or at least not with weapons that can fit in a Sparrow. So, don't risk it. It's like rock paper scissors; recognize what your enemy's strengths and weaknesses are, as well as your own."`
