imc: reject files with unfathomable sampling rates
With huge sampling rates, the table derivation method does not converge fast enough. While fixing it using e.g. Newton-Rhapson-like methods (the curve is nicely convex) is possible, it is much simpler to reject these cases. The value of 96000 was arbitrarily chosen as a realistic value, though 1000000 would still work and converge. Fixes ticket #3868.
