Improve image retrieve to optimize memory comsumption

[thomas-ernest]

Add parameters to arteitem._get_image_url in order to enable image resolution and text layer. Use 1920x1080 resolution and no text to populate fanart, use 320x180 resolution and text for thumbnails.

More details in discussion of issue #44 .

The memory consumption definitely wen down a lot (at least 100MB on usual list pages). But I there is only a thumbnail placeholder now and no preview icon on the left (just the full hd image in the background). I think downloading the small resolution does not work. In the console, I see:

GetImageHash - unable to stat url https://api-cdn.arte.tv/img/v2/image/qteyKntxDG2BaxEaXf6kdZ/320x180?type=TEXT

PS: I use Kodi 20.1 from Debian 12.

When I did my test I used 480x270, not 320x180 actually. I will update the PR accordingly. It is 4 times smaller instead of 6.

Works for me. For the reference how I checked memory consumption:

cd /sys/fs/cgroup
mkdir mem
cd mem
echo 170000000 > memory.max
echo 0 > memory.swap.max
# start kodi
pgrep kodi.bin > cgroup.procs 
while true; do cat memory.current; sleep 0.1; done

Thank you!
