- Rename Bits<T> to BitSet<T>.
- Implement set based helpers for BitSet<T>.
- When representing TargetTypes of ITargetable in various traits, use a BitSet<TargetableType> instead of HashSet<string> for better performance & reduced memory usage.
- Fix FieldLoader to trim input values when generating a BitSet<T>.
- Require T in BitSet<T> and BitSetAllocator<T> to be a class since it's just a marker value. This allows the JIT to instantiate generic code for these classes once, as they don't benefit from specialized code for T. (Typically JITs will generate shared code for all reference types, and unique code for every value type encountered).
This can be used to avoid several lookups for these traits, as well as allow Actor to provide specialised methods to deal with target types efficiently. This also reduces some code duplication.
To prevent the AI generating lag spikes by issuing too many orders in a single tick, it is now limited in how many orders can be issued per tick. Extra orders are queued. This allows the performance hit of issuing multiple orders to be spread out over several ticks.
The Warhead and WeaponInfo classes now maintain preconstructed sets of valid and invalid targets to speed up validation checks since LINQ Intersect no longer has to be called (which recreates the sets internally each time).
Fixed minor bugs in the AI where it was repeating the validation logic but failing to account for invalid targets.
There was an issue where HackyAI would try to build buildings
at old base location and would fail, unless it was placed at the
same place where the old MCV was.
