NNS init CSV parser no longer accepts dissolve delay s / maturity e8s equivalent

NNS init CSV parser no longer accepts dissolve delay s / maturity e8s equivalent: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). I'm using add all neurons from csv file to bootstrap NNS governance with a set of initial neurons (similar to rs/nns/integration…

The task

I'm using `add_all_neurons_from_csv_file` to bootstrap NNS governance with a set of initial neurons (similar to `rs/nns/integration_tests/src/neurons.csv`). I want each neuron in that CSV to have a configurable dissolve delay and an initial maturity.
