[Halld] Updated Translation Table

[David Lawrence]

Hi All,

  This is a head’s up that I just added a new translation table entry to the CCDB that includes
all of the DIRC channels as provided by Justin. This is significant for a couple of reasons.
One of them being that the DIRC increases the channel count from ~23k to ~37k. 

The other is that the procedure used to produce the XML file is somewhat new. It was generated
from the SQLite DB file that has been updated to include run range information. The DB file
was first updated by mining data from the CCDB, then the DIRC channels were added, then 
the XML file was generated and inserted into the CCDB. Note that ALL future changes to the TT
should be done in the SQLite DB first and the XML then generated from that. Please contact me 
if you need help with this.

Both Justin and I have done some testing and it seems the new TT does not break anything.
It is marked as valid only for runs >=60000 in the CCDB so people generally will not be
affected by it until they start processing files from the upcoming RunPeriod-2019-01 data set.

Thanks to Justin for doing a lot of the heavy lifting on getting all of the DIRC channels into the tt.db


Regards,
-David
