[5.0/x64] FFT Splitter missing sliders

[yehar]

How to reproduce bug:
- Add the FFT splitter effect to some channel that has audio
- Try changing the frequency

There should be a change in the output when changing the frequency but there is not. FFT Splitter no longer has sliders for destination channel. Seems like it is a capitalization bug of "slider" vs. "Slider" as an old version (https://stash.reaper.fm/oldsb/10148/fft-splitter) has:

slider1:2<0,3,1{1024,2048,4096}>FFT size
slider2:5000<0,20000,1>split freq
slider3:0<0,4,1{1/2,3/4,5/6,7/8}>low band dest
slider4:1<0,4,1{1/2,3/4,5/6,7/8}>high band dest

and the current version has:

slider1:2<0,4,1{1024,2048,4096,8192}>FFT Size
slider2:5000<0,20000,1>Split Frequency (Hz)
Slider3:0<0,4,1{1/2,3/4,5/6,7/8}>Low Band Destination
Slider4:1<0,4,1{1/2,3/4,5/6,7/8}>High Band Destination
// slider5:0<0,1,0.1>Debug

I grepped everything under c:\Users\Olli\AppData\Roaming\REAPER\Effects for "Slider" and only found the bug in FFT Splitter.
