Add new module: APOD (Astronomy Picture of day)

[InfiniteVerma]

Using one of NASA's API, APOD, the telegram bot can provide the user with

• An astronomy photo

• Title to the image

• An explanation as to why that particular photo is the photo of the day

• Author (and copyright)

• Date (the photo was taken)

Example: https://api.nasa.gov/planetary/apod?api_key=DEMO_KEY If you agree, I'd wish to work on this.
