Add a battery monitor middleware

[mano8]

Describe the solution you'd like
Introduce a battery monitor middleware to the vemonitor_m8 package that leverages inputs from solar batteries (such as voltage, current, and temperature). The middleware should perform the following functions:

- **Global Battery Status**: Determine whether the battery is in a charge or discharge state by analyzing voltage and current data.

- **Charge Phase Identification**: Automatically detect the current charging phase (e.g., bulk, absorption, float) based on voltage and current patterns.

- **Charging Control**: Monitor voltage and current during charging to ensure they are within safe limits for the specific battery type. The middleware should raise alerts if parameters exceed recommended values.

- **Discharging Control**: Ensure that the battery's discharge current does not exceed the maximum safe limit. Generate warnings or actions if this limit is approached or surpassed.

- **Temperature Compensation** (Optional): If input data lacks temperature compensation, apply a compensation factor based on the battery type to correct voltage and current readings accordingly. This ensures accurate monitoring and control, particularly in varying environmental conditions.
