Using std::chronothis example measures processing times of libtssi2 compares to:

void read(span<const char> data) {
	for (auto v : data) {}
}

Only the time spent in libtssi2 or readis measured. Disc to memory transfers are omitted. Data is processed in 1MB chunks.

All tests were conducted on a HP Spectre x360 with Intel Core i7-7500U.
