Caller.py Spotify API GET /search bug if multiple types as params of caller agent output

[Chuck1823]

If the output of the caller agent looks something like:

Caller:
Operation: GET
Input: {
"url": "https://api.spotify.com/v1/search",
"params": {
"q": "Mariah Carey",
"type": "track,album",
"market": "US",
"limit": "20",
"offset": "0",
"include_external": "audio",
"order": "popularity desc"
}
}

Which is valid according to the Spotify OAS, the current code in caller.py will fail because it can't handle multiple values for "type": "track,album". I am going to raise a pull request to fix this.
