C library providing BLAKE3

C library providing BLAKE3 hash function. BLAKE3 is a cryptographic hash function that is: - Much faster than MD5, SHA-1, SHA-2, SHA-3, and BLAKE2. - Secure, unlike MD5 and SHA-1. And secure against length extension, unlike SHA-2. - Highly parallelizable across any number of threads and SIMD lanes, because it's a Merkle tree on the inside. - Capable of verified streaming and incremental updates, again because it's a Merkle tree. - A PRF, MAC, KDF, and XOF, as well as a regular hash. - One algorithm with no variants, which is fast on x86-64 and also on smaller architectures.
