Because the quality of linear converters is so poor, I have not
even attempted to optimise or even profile it.
I notice that it runs about 5 times faster than SRC_SINC_FASTEST
and on reflection, it should probably be 20 times faster. However,
I really didn't even expect anyone to use SRC_LINEAR. It was added
for completeness, to show how bad linear converters are.
