[tor-commits] [onionperf/master] Add --date-prefix command line switch.

[karsten@xxxxxxxxxxxxxx]

commit 0025fef345803ad8ea0695181622e66530b2278d
Author: Philipp Winter <phw@xxxxxxxxx>
Date:   Fri May 29 16:00:24 2020 -0700

    Add --date-prefix command line switch.
    
    The switch tells OnionPerf to prepend yesterday's date to the analysis
    output file.  This new switch is mutually exclusive with --date-filter.
    
    This fixes <https://bugs.torproject.org/29369>.
