Fix to PIDe filtering problem
Problem
The old version of this code was doing the PIDe inversion by running filter_anti_pid_e. This functionality has been moved to this this builder.
Consequences
The filtering function was filtering by PID from [-1,+1] as shown below:
the intended cut should be in [-1, 1.5]. This is expected to increase the bandwidth.
Rates
The bandwidth W.R.T the full RD lines is attached. The table concerning the current module is below:

Bandwidth
The bandwiths are:
Before: 595 Mb => 235 Mb After : 604 Mb => 239 Mb
It ran over 568000 events with a rate of 1.3 MHz. The increase in bandwidth is 9 Mb. However the last MR showed a decrease of -29 Mb. Thus the net decrease should be 20Mb with both MRs combined. The compression was done with zstd -3
