TrigCost: Add jo to calculate EB weights

Since we cannot calculate weights online (no L1 prescales available) this JO can be run right after.

Now we don't have Run3 EB files, so there is an option to run on Run2 AOD and TDT.

Calculated weights will be saved to EnhancedBiasWeights_RUNNUMBER.xml file. For example:

<?xml version="1.0" encoding="us-ascii"?>
<run>
<weights>
<weight n="0" n="22841" unbiased="0"/>
<weight n="1" n="560" unbiased="0"/>
<weight n="2" n="479349" unbiased="1"/>
<weight n="3" n="5" unbiased="0"/>
<weight n="4" n="5710" unbiased="0"/>
<weight n="5" n="4568" unbiased="0"/>
</weights>
