fix: use `opj_uint_ceildiv` instead of `opj_int_ceildiv` when necessary

There are a bunch of loc where we can see a usage of `opj_int_ceildiv`:
```
(OPJ_UINT32)opj_int_ceildiv((OPJ_INT32)a, (OPJ_INT32)b);
```
where a & b are `OPJ_UINT32`.

This can lead to overflow/underflow for some a/b combinations.
Replace those calls by `opj_uint_ceildiv` instead to always get a correct result.

This also allows some valid single tile images with huge tile size to be decoded properly.
Fix #1438
