update sno_charge to prevent nan when charge is negative

This commit updates the charge spectrum initialization to convolve the charge
distribution over a wider range to make sure that we have a nonzero probability
of observing charges all the way down to qlo.

The reason for this is that previously for some negative charges the
probability of observing that charge was zero, which was causing the likelihood
to return nan.
