   swscale/ops_internal: fix ff_sws_pack_op_decode()
   This function was assuming that the bits are MSB-aligned, but they are
   LSB-aligned in both practice (and in the actual backend).
   
   Also update the documentation of SwsPackOp to make this clearer.
   
   Fixes an incorrect omission of a clamp after decoding e.g. rgb4, since
   the max value range was incorrectly determined as 0 as a result of unpacking
   the MSB bits instead of the LSB bits:
   
    bgr4 -> gray:
      [ u8 XXXX -> +XXX] SWS_OP_READ         : 1 elem(s) packed >> 1
      [ u8 .XXX -> +++X] SWS_OP_UNPACK       : {1 2 1 0}
      [ u8 ...X -> +++X] SWS_OP_SWIZZLE      : 2103
      [ u8 ...X -> +++X] SWS_OP_CONVERT      : u8 -> f32
      [f32 ...X -> .++X] SWS_OP_LINEAR       : dot3 [...]
      [f32 .XXX -> .++X] SWS_OP_DITHER       : 16x16 matrix + {0 3 2 5}
   +  [f32 .XXX -> .++X] SWS_OP_MIN          : x <= {255 _ _ _}
      [f32 .XXX -> +++X] SWS_OP_CONVERT      : f32 -> u8
      [ u8 .XXX -> +++X] SWS_OP_WRITE        : 1 elem(s) planar >> 0
        (X = unused, + = exact, 0 = zero)
