Switch back to the FIR256 filter by default

There is a surprisingly noticeable amount of static caused by the IIR filter in
particular circumstances. The 256-point filter is only slightly slower, but the
frequency response should be good enough to use as a default for now.

 ## decode-filter: (global)
 #  Specifies the all-pass filter type for UHJ decoding and Super Stereo
 #  processing. Valid values are:
-#  iir - utilizes dual IIR filters, providing a wide pass-band with low CPU
-#        use, but may exhibit some low-level distortion.
 #  fir256 - utilizes a 256-point FIR filter, providing more stable results but
 #           exhibiting attenuation in the lower and higher frequency bands.
 #  fir512 - utilizes a 512-point FIR filter, providing a wider pass-band than
 #           fir256, at the cost of more CPU use.
