    keyword=DAQ modifications

    With the RC's permission I made two minor modifications:

    1. Added the event type to the datastream for ROC3, ROC14 (L-arm) and
    ROC1, ROC2 (R-arm). This comes as the 5th word after the header
    0xfabc0005 which previously was 0xfabc0004. In ROC14 it is the 2nd word after
    the header 0xfadcb0b4

    2. I deleted the buffered mode from the list of possibilities available to shift workers.
    These DAQ configs still exist, but only an "expert" can select them. So, you can
    only run unbuffered for now, on both spectrometers.

    Runs up to 20591 / 1591 were test runs.
    More info: vxWorks timestamps, which were there since the start, are the 4th
    word after 0xfabc0004 (now 05) in fastbus, and 1st word after 0xfadcb0b4 in roc14.
    The "CODA event type" is always the event type of the first ROC in the readout
    which is usually ROC3 on L-arm and ROC1 on R-arm.
