Couldn't use RTS CMS image urls with Play SRG image service

[pyby]

Issue type

Incorrect content result

Description of the problem

44 is moving the whole library to one common image service: Play SRG image service.

Issue found with image urls from rts.ch CMS.

With 18.0.0 library release, the current fix is to not used Play SRG image service for RTS CMS image urls. The business unit scaling image service is still used, using the convention of https:[BU].ch/[image path]/scale/width/[width].

Waiting an image service update from RTS in 2023 Q3 or Q4.

Code sample

[[self.dataProvider mediaWithURN:@"urn:rts:audio:14145940" completionBlock:^(SRGMedia * _Nullable media, 
        // "imageUrl" = "https://www.rts.ch/2021/04/30/14/43/7978319.image/16x9"

        NSURL *imageURL = [self.dataProvider URLForImage:media.image withWidth:SRGImageWidth320];
        // Using Play SRG image service: "https://il.srgssr.ch/images/?imageUrl=https://www.rts.ch/2021/04/30/14/43/7978319.image/16x9&format=jpg&width=320"

        UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:imageURL]];
        // 16:9 ratio or a square ratio expected, but with correct content.
        // Currently, it's the raw image returns.

    }] resume];

RTS audio image urls has 16x9 in its path, but it's not used correctly by RTS CMS image service: internal SRG ticket created.

[pyby]

The related internal ticket for RTS as been tackled by @bgaudaen. Few image caches could exist but now, the RTS image urls are compatible with Play SRG image service.

The workaround introduced in #44 could be removed.

[pyby]

We'll try to clean RTS show image cache, by updating the image urls. Tested in Play RTS iOS, wrong ratio image still delivered.

Script to get all Play RTS main show images:

#!/bin/bash

# Initialize an empty array to store show image URLs
show_image_urls=()
# Initialize an empty array to store show image IDs
show_image_ids=()

# Define the URL to remove
url_to_remove="https://ws.srf.ch/asset/image/audio/8b32fd87-459e-40f1-9519-ba0cbb01f34e/NOT_SPECIFIED.jpg"

# Define the API URLs
api_urls=(
