The CycleComponent should have 2 states --
[cycle_sin, cycle_cos]
, and associated dims. I had incorrectly assigned it only a single initial state, so the cosine component was forced to always be zero at initialization.In addition,
model.param_dims
will now correctly return named dims for the cycle initial state.Adds a test of model initial states against statsmodels to catch issues like this in the future.
