Update athom-smart-plug.yaml - Add additional Energy Statistics

[Roving-Ronin]

• Update project version number.
• Linked substitution 'Device Description' to esphome comment: field
• Update SNTP update interval to use substitution to set, that was overlooked previously.
• Update SNTP to define pool.ntp.org servers to use, can be changed to country/region pool servers in substitutions.
• Make log level changeable using value declared in substitutions.
• Add Energy Yesterday, Weekly, Monthly sensors (provided by https://github.com/dentra/esphome-components/tree/master/components/energy_statistics - if preferred the component could be copied to Athom Repo instead)
• Amend 'Total Daily Energy' sensor to 'Total Energy Today' to keep in line with 'Total Energy Yesterday/Week/Month' ('Total Yesterday Energy' is incorrect grammar and stops the use of that format).
• Amend 'Energy' sensor to be 'internal', as serves no purpose, has no timeframe associated with it and resets at boot & reflashing. Made changeable via hide_energy_sensor subsitution (true/false)
• Added network component enable_ipv6 as an option, controlled via ipv6_enable in substitutions, set to 'false' by default.

Edit: Replace 'Total Energy Today' with Dentra Component that provides this information, but is persistent between reboots / reflashing versus the previous version that reset to zero every time.

Additional Pull / Patch to Smart Plug v3: 1) Update the Wifi Signal Percentage to include device_class: "" 2) Also update template to include missing comments for the function of subsitutions.

[Roving-Ronin]

Add - Update athom-garage-door.yaml

1) Update to be in sync with other devices templates, such as smart plug v3, for use of substitutions and use of sntp servers, commenting to explain what substitutions do.

2) Add device_class: "" fix to the WiFi Signal Percentage sensor

[Roving-Ronin]

Add 'id: wifi_strength' to the sensor that provides the WiFi Strength as a Percentage (%), to allow people to disable it if desired, in their local device configuration file.
