Module extension

Fast OT extension using optimized [IKNP03] (semi-honest) or [KOS15] (malicious) protocol.

The protocols are optimized for the availability of aes and avx2 target features for the semi-honest protocol and additionally pclmulqdq for the malicious protocol.

Batching

The protocols automatically compute the OTs in batches to increase throughput. The DEFAULT_OT_BATCH_SIZE has been chosen to maximise throughput in very low latency settings for large numbers of OTs. The batch size can changed using the corresponding methods on the sender and receiver (e.g. OtExtensionSender::with_batch_size).
