Optim: GetWaterFactors now maintains a stable transform cache - We now use a burst job to gather transform info for all players (ends up being fast enough to not care) - Updated perf test to count for a "warmup" run, since we incrementally build the transform cache Previous updates slowed down code from 9ms to 12ms, this optim brings us back to ~7ms for 10k cases and enables more optims Tests: unit tests
