Generate pseudoprimaries using multiples

        sfpseudoprim < in.rsf > out.rsf mul=mul.rsf verb=n stack=y both=n jumpo=1 jumps=1
The axes in the input are {offset,shot,frequency}
The axes in the output are {offset,shot,frequency}
Requirement: offset interval = shot interval

bool both=n [y/n]
receiver flag, if y, receiver with both sides
int jumpo=1
jump in offset dimension, only for stack=n
int jumps=1
jump in shot dimension, only for stack=n
string mul=
auxiliary input file name
bool stack=y [y/n]
stack flag, if y, no common pseudoprimary gather
bool verb=n [y/n]
verbosity flag
