Adding preliminary hit smearing and hit killing

[EBerzin]

This includes hit efficiency corrections derived from two runs, and the corresponding steering files: PhysicsRun2021MCRecon_KF_WithSpacing_pass3_HitKill_14232.lcsim, PhysicsRun2021MCRecon_KF_WithSpacing_pass3_HitKill_14464.lcsim.

PhysicsRun2021MCRecon_KF_WithSpacing_pass3_HitSmear.lcsim implements the full smearing chain, including position, hit time, and track time smearing. This required adding a new TrackTimeSmearer driver, as well as modifications to the existing smearers to ignore data hits.

Here are the changes that need to applied to the recon steering files to get the correct MC track and cluster times.
The EcalTimeCorrection driver is already part of the steering files, but has to be configured a bit differently.

<driver name="EcalTimeCorrection" type="org.hps.recon.ecal.EcalTimeCorrectionDriver">
        <additionalShift>13.3</additionalShift>
</driver>

In RawTrackerHitFitterDriver set tsCorrectionScale to 165 (should be 120 before this change)

<tsCorrectionScale>165</tsCorrectionScale>

This PR should be merged after #1143 which includes all other necessary changes.

For the next MC production, I assume we will want to use:
PhysicsRun2021MCRecon_KF_WithSpacing_pass3_HitSmear.lcsim

The PR looks good to me, but we will need to add the lines Sarah pointed out above to the above steering file before we can proceed. When you get a chance, can you make those changes? Would be great if we could get this running before the weekend, if possible...

Looks good to me!

Looks good to me too, thanks!
