all currents and update_states should be written to handle a single compartment. This means that v will be a scalar.
Use an select-case instead. Internally, we then vmap the update_states, and JAX is smart enough to automatically case the cond to where.

Added a simple LIF channel and also one that is potentially differentiable, although I have not tested this.
Probably needs some tests and scrutiny.
