in hops.util.findfringe
currently fourier interpolation is used to zoom into the fringe location but this is inefficient to apply to the entire search space
add additional stage quadratic interpolation
or put fringe at DC and do a limited supersampling, or do a direct search
can plot statistical uncertainties as well
