liboqs: Add library for quantum-safe cryptographic algorithms

liboqs is an open source C library for quantum-safe cryptographic
algorithms.

liboqs provides:

- a collection of open source implementations of quantum-safe key
  encapsulation mechanisms (KEMs) and digital signature algorithms
- a common API for these algorithms
- a test harness and benchmarking routines

liboqs is part of the Open Quantum Safe (OQS) project, which aims to
develop and integrate into applications quantum-safe cryptography to
facilitate deployment and testing in real world contexts. In particular,
OQS provides prototype integrations of liboqs into protocols like TLS,
X.509, and S/MIME, through our OpenSSL 3 Provider and we provide a
variety of other post-quantum-enabled demos.
