Method insert

Not thread safe. Only call from single producer thread. Note: key must *not* be in hash already, and must be exactly one larger than the previously inserted key value.

    // one larger than the previously inserted key value.
    void insert(std::uint64_t key, TValue* value)

        IndexEntry* idxEntry;

    // Thread-safe, but if somebody can remove the key while find() is
    // in progress, then any returned value is not guaranteed to correspond
