These arrays are currently accessed via uint16_t* pointers
although nothing guarantees their alignment. Furthermore,
this is problematic wrt the effective-type rules.
Fix this by using a union of arrays of uint8_t and uint16_t.

max_bin_idx can be at most LMCS_MAX_BIN_SIZE - 1 here,
so pivot[LCMS_MAX_BIN_SIZE + 1] may be accessed,
but pivot has only LCMS_MAX_BIN_SIZE + 1 elements
(unless the values of pivot were so that it is always
assured that pivot[LCMS_MAX_BIN_SIZE] is always < sample
(which it is iff it is always < 2^bit_depth - 1)).
So reorder the checks.

The PPS should be used instead of the SPS to get the current picture's
dimensions. Using the SPS can cause issues if the resolution changes
mid-sequence. In particular, it was leading to invalid memory accesses
if the resolution decreased.
Patch replaces sps->{width,height} with pps->{width,height}. It also
removes sps->{width,height}, as these are no longer used anywhere.
