wavenc sinkpad caps:

      audio/x-raw-int
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 2 ]
             endianness: 1234
                  width: 32
                  depth: [ 25, 32 ]
                 signed: true
      audio/x-raw-int
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 2 ]
             endianness: 1234
                  width: 24
                  depth: [ 17, 24 ]
                 signed: true
      audio/x-raw-int
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 2 ]
             endianness: 1234
                  width: 16
                  depth: [ 9, 16 ]
                 signed: true

This allows, for example, the creation of a 25-bit depth file.  I'm pretty sure
this is not what any user wants, except perhaps in an
enable-crazy-shit-that-will-only-cause-problems mode.  In the interest of
sanity, I'm removing the ranges and replacing them with sane values.

Notably, the pipeline 'filesrc ! flacdec ! audioconvert ! wavenc ! filesink'
will create a 25-bit-depth file, since flac outputs 24/32, and wavenc won't
accept it, even though it's actually a common format.
