[SoundCloud] Add utility methods to get images from track JSON objects and image URLs 

These new public and static methods, added in SoundcloudParsingHelper,
getAllImagesFromArtworkOrAvatarUrl(String) and
getAllImagesFromVisualUrl(String) (which call a common private method,
getAllImagesFromImageUrlReturned(String, List<ImageSuffix>, List<Image>)),
return an unmodifiable list of JPEG images containing almost every image
resolution provided by SoundCloud except the original size and the tiny
resolution (for artworks and avatars, as the image size is 20x20 for artworks
and 18x18 for avatars, so very close to or equal to the t20x20 resolution):

- for artworks and avatars:
  - mini: 16x16;
  - t20x20: 20x20;
  - small: 32x32;
  - badge: 47x47;
  - t50x50: 50x50;
  - t60x60: 60x60;
  - t67x67: 67x67;
  - large: 100x100;
  - t120x120: 120x120;
  - t200x200: 200x200;
  - t240x240: 240x240;
  - t250x250: 250x250;
  - t300x300: 300x300;
  - t500x500: 500x500.

- for visuals/user banners:
  - t1240x260: 1240x260;
  - t2480x520: 2480x520.

Duplicated code in two methods of SoundcloudParsingHelper
(getUsersFromApi(ChannelInfoItemsCollector, String) and
getStreamsFromApi(StreamInfoItemsCollector, String, boolean)) has been merged
into one common private method, getNextPageUrlFromResponseObject(JsonObject).

SoundCloud avatars and artworks are almost squares
When we get non-square pictures, all these images variants are still squares, except the
original and the crop versions provides images which are respecting aspect ratios.
The websites only use the square variants.
t2400x2400 and t3000x3000 variants also exists, but are not returned as several images are
uploaded with a lower size than these variants: in this case, these variants return an upscaled
version of the original image.
