ms_srs: allow + operator when specifying CSV columns

this allows to sum dl_brate and ul_brate and perform
the known operations, like max, average, etc. on both
UL and DL bitrate combined

For examples, with this CSV ..

time;cc;pci;earfcn;rsrp;pl;cfo;dl_mcs;dl_snr;dl_turbo;dl_brate;dl_bler;ul_ta;ul_mcs;ul_buff;ul_brate;ul_bler;rf_o;rf_u;rf_l;is_attached
1999;0;1;3400;-67;59;913;27;29;0.50;10432.000000;0;2.6;20;0.0;10848.000000;0;0.0;0.0;0.0;1.0
2998;0;1;3400;-67;59;912;28;29;0.50;2136.000000;0;2.6;20;0.0;1680.000000;0;0.0;0.0;0.0;1.0
3997;0;1;3400;-69;61;909;28;29;0.50;2136.000000;0;2.6;20;0.0;1680.000000;0;0.0;0.0;0.0;1.0

.. one could calculate the average of DL and UL bit rate with:

ue.verify_metric(1e6, operation='avg', metric='dl_brate+ul_brate', criterion='gt', window=test_duration)

and veriy that it's average is greater than 1 Mbit/s
