CI/CD Signals

Currently, the CI/CD uses L1 and E5b intenstively. We should introduce a third frequency

• verify (in CI) that the library operates correctly using L2/L1 instead of L1/L5
• if we ever Fuzz Test #95, it could be interesting to switch between L2/L1 and L1/L5, possibly erraticly
• inquire L2/L5 scenario ?
• A third frequency allows testing Extra Wide DD #102
