How to time OT for SP-LUT

[GeekAlexis]

I tried to benchmark OT in psi_phasing using SP-LUT, but it is not clear what OT is being used for SP-LUT in default. It looks like we have to add #define use_kk_ot manually in ABYConstant.h to actually use KK OT, but what OT is used in default then? Also, define use_kk_ot makes the runtime actually slower. #define use_pipelined_AES_NI doesn't even compile.
