Add run_ukirt_pipeline subroutine to new submodule

This invokes JSA::WrapDR::run_pipeline in a manner suitable for
the UKIRT archive.  It adds the --skiperror command line option
and determines the name of the log file written by ORAC-DR.
Add --calobs command line option

This new option can be used to identify the calibration
observations.  They are then reduced first with a separate
invocation of ORAC-DR.
Combine the log files from the two runs of ORAC-DR

Note that the subroutine which actually combines the files
is very dependent on the current format of those HTML files.
