[Halld-offline] Emulation mode changes

[David Lawrence]

Hi All,

 I have just pushed a set of changes to the DAQ library onto the “davidl” branch of sim-recon.
Because there are several changes that might break something, I’m holding off submitting a
pull request until some people have had a chance to test out the changes. Kei has already
volunteered to test this out, but if others wanted to have a look too, that would be swell.

These changes clean up the emulation configuration parameters and bring the  configuration
options for f250 and f125 emulation into better alignment. The original motivation was to allow
emulation of mixed-mode data. In particular, the triplet polarimeter data was always taken
with mode 8, regardless of the mode of the other f250 modules. (Thanks Kei for pointing this out.)
Originally, emulation was done only if no mode 7 data existed for any channel. The default behavior
now is to check channel by channel and do emulation only for channels that have no mode 7 data.
In addition, there are now variables to force emulation to always happen or never happen.
I’ve tried to summarize the changes to configuration parameters below. 

Please let me know if you have any questions.
