init_state wrongly initialized as `init_value` in SCIF model

^{Originally posted by nnbtam99 June 1, 2023} Hi Lava team,

I'm new to the neuromorphic computing paradigm and I have a quick question regarding the implementation of SCIF model https://github.com/lava-nc/lava-optimization/blob/74e58b5f361eac79cea51b1d748529863d4c66b7/src/lava/lib/optimization/solvers/generic/sub_process_models.py#LL69C1-L69C1

I just wonder why we set the default value of init_state variable as init_value for SCIF neuron model.

Thank you very much in advance! Tam
