fix: reduce string comparisons in ADC decoding, cleanup

[baltzell]

Note, this assumes unique crate/slot/channel in all /daq/fadc CCDB tables. Now, the first match wins. Previously the last match won. For run 5038, the RF/LTCC::adc banks have a resulting difference, which will be addressed by fixing CCDB tables to be unique.

Note, this was a component of #1051.

The LTCC/RF discrepancy is due to /daq/fadc/rf and /daq/fadc/ltcc CCDB tables, crate/slot/channel=19/18/15:

clara2501> ccdb dump /daq/fadc/ltcc | grep -E '19[[:space:]]+18[[:space:]]+15'
  19           18           15           79.6         3            15           50           1280            400
clara2501> ccdb dump /daq/fadc/rf | grep -E '19[[:space:]]+18[[:space:]]+15'

And the RAW::tdc discrepancy looks like this:

* NODE * group =  20000, item =  12, type = 11, size =       63
         crate :         20        60        64        64        64        64        64
          slot :         20        16        16        16        16        16        16
       channel :         15        20         8         8         8         8         8
         order :         83       -16       -46        52      -106       -13        84
           TDC :        114         0         0         0         0         0         0

* NODE * group =  20000, item =  12, type = 11, size =       63
         crate :         60        20        64        64        64        64        64
          slot :         16        20        16        16        16        16        16
       channel :         20        15         8         8         8         8         8
         order :        -16        83       -46        52      -106       -13        84
           TDC :        114         0         0         0         0         0         0

If it ends up in RAW::tdc/adc, then it's not found in CCDB. So, this one must originate from #1065.

The RF::adc-only discrepancy for RG-M looks like this:

Bank.show RF::adc
* NODE * group =  21700, item =  11, type = 11, size =       30
        sector :          1         1
         layer :          1         1
     component :          3         4
         order :          0         0
           ADC :       9479       261
          time :    95.1250  132.5000
           ped :        971      2674

* NODE * group =  21700, item =  11, type = 11, size =       30
        sector :          1         1
         layer :          1         1
     component :          3         4
         order :          0         0
           ADC :      10371     34556
          time :     0.0000    0.0000
           ped :        200       200

Maybe/hopefully this will be explained by picking up the pedestal/threshold form /daq/fadc/ltcc in the former case.

Another overlap in /daq/fadc/ec and /daq/fadc/ltcc for slot 18, channels 12-15, crates 1, 7, 13, 19, 25, 31 (one for each sector). As /daq/tt/ec doesn't contain these overlapping channels, they should probably be disabled in /daq/fadc/ec by setting one of their indices to bogus.
