src and dst are only 8-bit-aligned, so accessing them as uint16_t causes
SIGBUS crashes on architectures like sparc.
This fixes ubsan runtime error: load of misaligned address for type
'const uint16_t', which requires 2 byte alignment

This can happen if s->ls changes from 0 to 1, but picture allocation is
skipped due to s->interlaced.
In that case ff_jpegls_decode_picture could be called even though the
s->picture_ptr frame has the wrong pixel format and thus a wrong
linesize, which results in a too small zero buffer being allocated.
This fixes an out-of-bounds read in ls_decode_line.

Due to this typo max_center can be too large, causing nlsf to be set to
too large values, which in turn can cause nlsf[i - 1] + min_delta[i] to
overflow to a negative value, which is not allowed for nlsf and can
cause an out of bounds read in silk_lsf2lpc.

If the chroma components are subsampled, smaller buffers are allocated
for them. In that case the maximal block_offset for the chroma
components is not as large as for the luma component.
This fixes out of bounds writes causing segmentation faults or memory
