Update ZLIB to v1.2.12-p0 (#545)

Write access (compression) in zlib has a bug, we need to update to 1.2.12 for the security fix

From https://zlib.net/

> Version 1.2.12 has these key improvements over 1.2.11:
>
> - Fix a deflate bug when using the `Z_FIXED` strategy that can result in out-of-bound accesses.
> - Fix a deflate bug when the window is full in `deflate_stored()`.
> - Speed up CRC-32 computations by a factor of 1.5 to 3.
> - Use the hardware CRC-32 instruction on ARMv8 processors.
> - Speed up crc32_combine() with powers of x tables.
> - Add `crc32_combine_gen()` and `crc32_combine_op()` for fast combines.
