digest: CRC32 and Adler32 hashes for bytestrings

This package provides efficient hash implementations for strict and lazy bytestrings. For now, CRC32 and Adler32 are supported; they are implemented as FFI bindings to efficient code from zlib.

Flags

Manual Flags

Name	Description	Default
have_builtin_prefetch	The cxx compiler has the __builtin_prefetch intrinsic.	Disabled
have_mm_prefetch	Targeting X86 and the compiler has the _mm_prefetch intrinsic.	Disabled
have_sse42	Can be enabled to improve performance of CRC32C if targeting X86 and the compiler has the _mm_crc32_u{8,32,64} intrinsics.	Disabled
have_arm64_crc32c	Targeting ARM and the compiler has the __crc32c{b,h,w,d} and the vmull_p64 intrinsics.	Disabled
have_strong_getauxval	The system libraries have the getauxval function in the sys/auxv.h header. Should be true on Linux and Android API level 20+.	Disabled
have_weak_getauxval	The compiler supports defining getauxval as a weak symbol. Should be true for any compiler that supports attribute((weak)).	Disabled
