Add Zstandard compression support
...
Implements zstd as an alternative to LZMA for data block and
subchannel compression using the allocated compression IDs 4
(kCompressionZstd) and 5 (kCompressionZstdCst).
Adds zstd v1.5.7 as a bundled submodule with a static library
build including x86_64 assembly fast path for decompression.
Write path selects zstd or LZMA based on the zstd option.
Subchannel blocks use zstd+CST instead of LZMA+CST when enabled.
LZMA properties header is only written for LZMA-based compression
types, preventing format corruption in zstd-compressed images.
Activated via options string: "zstd=true;zstd_level=19".
Default remains LZMA for backwards compatibility.
Tested: SHA-256 verified lossless roundtrips across 9 disc systems
(Dreamcast, Saturn, Mega CD, PC Engine CD, Neo Geo CD, PS1, PS2 CD,
PS2 DVD) and PS1 SBI subchannel preservation with zstd+CST.

Reserve compression IDs 4 and 5 for Zstandard (zstd)
...
Adds kCompressionZstd = 4 and kCompressionZstdCst = 5 to the
CompressionType enum, following the existing LZMA/LzmaCst pattern.

Support static and shared library builds via BUILD_SHARED_LIBS
...
Replace hardcoded SHARED in add_library() with the standard CMake
BUILD_SHARED_LIBS variable. Default remains shared for backwards
compatibility.
-DBUILD_SHARED_LIBS=OFF → static library (libaaruformat.a)
-DBUILD_SHARED_LIBS=ON → shared library (libaaruformat.so, default)
Also define _POSIX_C_SOURCE=200809L on non-Windows platforms so that
POSIX functions (strdup, fseeko, ftello) are properly declared when
building with CMAKE_C_EXTENSIONS=OFF (strict C99 mode).
Tested: shared + static with GCC, static with musl cross-compiler.

Fix uninitialized EDC bytes for Mode 2 Form 2 NoCrc sectors
...
When reading back Mode 2 Form 2 sectors with SectorStatusMode2Form2NoCrc,
the 4-byte EDC field at bytes 2348-2351 was left untouched. Since the
caller's buffer may contain arbitrary data, this results in non-deterministic
output for those bytes.
The NoCrc status indicates the original disc had no CRC (zeroed EDC).
The fix adds the missing else branch to zero the EDC field, matching
the behavior that Mode2Form2Ok already has via aaruf_ecc_cd_reconstruct.
Both DDT v1 and v2 code paths are fixed.
