Program bitcode on device.
Parameters
----------
boffile : string
Filename of the bitcode to program. If 'latest-build' then
use the current build. Default is 'latest-build'.
do_cal : bool
If true then do ADC core calibration. Default is True.
iface : string
Network interface connected to the data network.
verbose : int
The higher the more verbose, control the amount of output to
the screen. Default is 10 (probably the highest).
