Feature: DPL: support setups without power meter

without a power meter configured, the DPL now sets the base load as the inverter limit if the battery charge allows it. it also takes solar-passthrough into account, i.e., if the battery is in a charge cycle but the solar output (Victron MPPT) is significant, the solar power will be used up until the base load. if the battery reaches the full solar passthrough threshold, the DPL will match the inverter limit to the MPPT solar output.
