wookieejedi 50935e540e Fix scripting copy-paste bug and other minor optimizations (#7684) 
* Fix scripting copy-paste bug

The iterators for secondary banks for lua access had a copy-paste bug from primaries, so we should fix that. The early == -1 break masks it whenever a ship uses 3 or fewer secondary banks, which is probably why it went unnoticed.

Also add some additional low-hanging fruit optimizations.

* radar distance and other cleanup

* clang
