feat: writeFloat for seeding performance in SeedingPerformanceWriter.…

…cpp (acts-project#2654)

Store (floats) total efficiency, fake rate, duplicate rate and purity in output root file as it is done with ckf performance writer.
This is useful for using the seeding parameters in optuna automatic tuning.
