Noxonix protocol generation

[ardunn]

Do for protocol the same thing that BEEPDatapath does for cycler runs; a consistent interface with simple(r) access to the underlying objects. First try this approach on the Novonix protocol generation since it is the most accessible at the moment.

i.e., NovonixProtocol would inherit Protocol and would be used like

np = NovonixProtocol.from_parameter_file("protocol_parameter_file")

# edit protocol steps
np.edit_step("cv_hold_charge", 3)

# write the file
np.to_file(filepath_for_protocol_file)

@shijingsun-TRI if Xiao posts the code for the current novonix protocol generation I could start looking into this
