Deterministic testing

[termoshtt]

Some test fails randomly because they use random vectors without fixing its value via seed. This reduces the worth of auto-testing since we have to check the CI failure is due to bug in changes or due to random number.

TODO

• Add API to use any random number generator (RNG) in ndarray_linalg::generate random_*_using API for using given RNG #337
• Replace random vector generation in tests using fixed seed RNG Fix PRNG seed for random vectors and matrices in tests #338

[termoshtt]

Tests for LOBPCG still randomly fails due to it uses random in itself. It should accept to use specific RNG.
