Add support to service call target

[ristomatti]

This allows setting a target to a call-service action, e.g.

tap_action:
  action: call-service
  service: remote.send_command
  service_target:
    device_id: a6015bda1dfaf2b5a38f7eefeb050c06
  service_data:
    device: '37034509'
    command: 'FanSpeedUp'

Resolves #40.

The support lacked also from custom-card-helpers, hence I had to augment the type for CallServiceActionConfig and call a function directly from home-assistant-js-websocket.

Great timing, just after the migration to Typescript and GH actions.

You might want to send a PR to custom-card-helpers as well as they should really be supporting this too.

As a complete noob to HA custom cards and the ecosystem, this PR would not have been possible with strong TypeScript types. 👍

I'm not sure if I'll have time to dig into their contribution guidelines etc., I've already got (paid) work piling up 😅. Even this was unnecessary for my current use case but thought I'll make some use of the time spent twiddling with this.

@jcwillox Can we go with this or do you want to wait for custom-card-helpers to add the missing type?

Well, I'll be dammed someone already added support for this 2 months ago but they haven't released the update, custom-cards/custom-card-helpers@894aec4.
I'd recommend we just install from the latest commit, I've tested it and now we can just use hass.callService and remove those extra typings 😃.

pnpm add github:custom-cards/custom-card-helpers#ae86495

Oh boy. I'll have time to follow up on this after the holidays but you're welcome to pull in the changes to another branch and fix things up if you will. :)

Sure thing, I've already got the code from when I was checking to see if we could just use the latest commit from custom card helpers.

Thanks! One thing less on my TODO-list. 🙂
