This resolves #442 with a lot of new developments.

  • enable "external" triggers (i.e. triggers from other FW blocks besides the FC one)
  • enable multi-sampling within the FC block (resolves multi-trigger using fast control command block #142)
  • decoding of parent structure of ECONT packet and output of algo packet
  • ability to disable L1A following a charge injection command in order to test trigger ability
  • patch ROC parameter mapping deduction for parameters whose registers are out of our expected order (ROC.L1OFFSET is the important, motivating example in this case)
  • make sure the different elinks from the ECON-T have BX counters incrementing in step (done within the ECON-T/lpGBT alignment)
  • capture algo output from trigpath firmware block and decode it
  • interface with "single shot" mechanic in trigpath firmware that only lets one self-trigger from being sent onward to daq (necessary for these early, poorly-configured trigger algorithms which tend to accept too many events)

@tomeichlersmith
check that different links from same ECON-T are in time

@tomeichlersmith
draft trig timein function
aaf6939 
not observing charge pulse even on daq path right now so its not working
@tomeichlersmith
update charge timescan, able to observe pulse in daq path now

@tomeichlersmith
add in daq decoding to check we can see pulse

add in ability to change capture delay
@tomeichlersmith
hardcode channel choice, observing excess but not deducing pipeline

@tomeichlersmith
correct naming and description of max fields

@tomeichlersmith
fixup order of registers for a parameter
b415ac1 
two parameters (L1Offset and ExtData) have their registers out of our
assumed order, we enforce this order by using the param_minbit stored in
the reference mapping
@tomeichlersmith
align capture delay bump
