Fix DUO102 warnings

Added comments to ignore some because:

"Python uses the Mersenne Twister as the core generator. However, being completely
deterministic, it is not suitable for all purposes, and is completely unsuitable for
cryptographic purposes. Because the generator is deterministic this means attackers
can predict future values given a sufficient amount of previous values.

Normal random use is acceptable if the relevant code is not used for security or
cryptographic purposes."
