Allow user to specify more parameters for energy storage

[danielolsen]

The most important one here for our short-term work is duration, but while we're at it we could also allow specification for others (e.g. efficiencies). These are currently hardcoded in powersimdata.network.usa_tamu.usa_tamu_model.TAMU._set_storage(), and we would want to extend the functionality of powersimdata.input.change_table.ChangeTable.add_storage_capacity().

Another important thing to be able to model: storage losses. Sticking with the old MATPOWER/MOST table formats, there is a LossFactor that can be specified as a % of stored energy per hour. This is not currently interpreted by REISE.jl however.
