Vita3k Workbin File Repack

# Pseudocode
def repack_workbin(entries):
    # entries: dict key_hash: (type, value_blob)
    bucket_count = next_prime(len(entries) * 2)
    buckets = [None] * bucket_count
    for kh, data in entries.items():
        idx = kh % bucket_count
        while buckets[idx] is not None:
            idx = (idx + 1) % bucket_count
        buckets[idx] = (kh, data)
    # Write header + buckets + value section
