Kp 9fd0cc96a5 Use correct coefficient table for 11Khz sounds ... The new resampler sets upFactor to either `2` (for 22Khz sounds) or `4` (for 11Khz sounds). However, the logic to pick which coefficient table to use tested for `0` versus non-zero, so it always picked the coefficient table meant for 22Khz sounds, even when the sample was an 11Khz sound. This caused a high pitched ringing in sampled sounds. Switch to use an `enum class` to prevent using zero-vs-nonzero tests without a cast. Change the existing test to test for the 22Khz `enum` value, as originally intended. In testing, this eliminated the ringing effect in 11Khz sounds.
