[TASK][DOC] (libstfinv): specify meaning of offset dependent weight

The weight factors are applied in terms of signal amplitude not in terms of
signal energy. Where factors are to be applied to energy values, they have to
be squared prior to the operation.

the source wavelet correction filter is constructed. The option exp provides
means to add a weight factor ((r/1m)**k) to each signal, where r is the
receiver to source offset. This is used to compensate the decrease in signal
energy.

all traces will contribute at a similar level to the derived correction filter
after application of the weight factors.
