No 'version' key in the manifest file for custom integration 'amberelectric'

[CRCinAU]

When loading in a recent version of HA:

WARNING (MainThread) [homeassistant.loader] No 'version' key in the manifest file for custom integration 'amberelectric'. This will not be allowed in a future version of Home Assistant. Please report this to the maintainer of 'amberelectric'

Whilst not super urgent, would be preferable to fix early before things suddenly break :)

As futher, this will die on release 2021.6:

hass[327130]: 2021-04-08 17:08:53 WARNING (MainThread) [homeassistant.loader] You are using a custom integration amberelectric which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant
hass[327130]: 2021-04-08 17:08:53 WARNING (MainThread) [homeassistant.loader] No 'version' key in the manifest file for custom integration 'amberelectric'. As of Home Assistant 2021.6, this integration will no longer be loaded. Please report this to the maintainer of 'amberelectric'

Noting the impending blocking of custom components without a manifest, I've created a fork where I will do my best to get us to a point where it can be continued to be used.

Happy to work on any issues I can, and manage the fork, however am not a dev, so welcome any PR's.
