petrajectories drops the continue_status case

[Krastanov]

We should probably fix this

QuantumClifford.jl/src/petrajectory.jl

Lines 46 to 50 in 5fcf353

	function petrajectory_keep(state, circuit; branch_weight=1.0, current_order=0, max_order=1) # TODO a lot of repetition with petrajectory - dry out
	A = Accumulator{Tuple{typeof(state),CircuitStatus},typeof(branch_weight)}
	if size(circuit)[1] == 0
	return A()
	end

We probably want the accumulator to include

key: (state, continue_status)
value: branch_weight

I think for accumulators we need the inc! function to add that weight.

Not quite sure what is the good solution for the keepstate=False case
