Remove safe_mult related restrictions on beta #99

Closed ffreyer closed 2 years ago

ffreyer commented 3 years ago

Currently something like DQMC(model, beta=2.2, delta_tau=0.1, safe_mult=10) fails, because we require that N * safe_mult * delta_tau == beta. We can simplify this requirement to N * delta_tau == beta if we either

perform an irregular stabilization at the first (last?) time propagation or
disconnect time steps from stabilization

Note that global updates currently rely on having a fresh UDT transformation to work with
