Problem/Feature

With the addition of the template field on /chat/emotes?broadcaster_id=, there is a template field added to the API response, but isn't shown in twitch api calls. This adds it to the model so that it can unmarshal it.

Description of Changes:

• Adds template response

This doesn't fix the issue, because inside internal/api/api.go full response from apiResponse variable is assigned to data only on non-2xx codes:

twitch-cli/internal/api/api.go

Lines 104 to 107 in 7328a88

	if resp.StatusCode > 299 || resp.StatusCode < 200 {
	data = apiResponse
	break
	}

In all other scenarios, only data.Data is set and thus only content of the "data" array from the actual Helix call is returned and shown.
Given that, fields other than the "data" array will never be shown. I believe Twitch just didn't expect any other fields than data be returned on 2xx responses (unlike it was done in Kraken).

So anyway, a fix that makes it, so other fields than data can be returned would have to be made for this PR to work properly ;)
