Remove energy sensor from incompatible Ata devices

[vilppuvuorinen]

Proposed change

An AtaDevice has a boolean flag describing whether it supports energy
consumption metering. The flag was ignored resulting in sensor entities
reporting constant 0 kWh consumption. Not critical, but confusing for the user.

• Update pymelcloud dependency to support the has_energy_consumed_meter
  flag.
• Add ATTR_ENABLED_FN to sensor definitions for filtering out
  unsupported sensors.
• Fix typing issue in sensor constructor.
• Remove unused UnitSystem constructor parameter.
