Remove shorts from Subscriptions tab

[JaCzekanski]

This PR adds filtering of JSON nodes containing reelWatchEndpoint which is an indicator that given video is a reel/short. Due to the convoluted format of JSON responses, it might not cover all of the cases.

Reel playback seems broken on TVs and I don't really care about having them, as it's ofter reused content. Please note that it'll only work on the Subscriptions tab (which is the one I use the most). However, It should be pretty easy to extend it to other tabs and search results.

Great work, keen to see this merged - shorts are a real pain point for me

[JaCzekanski]

@FuriousBottle Is there any action needed from my side to have this PR merged?

@JaCzekanski sorry for the confusion, I am just an admirer, I don't have any authority here 😅

I tested the current "hardcoded path" approach and recursive search - the latter is slightly slower (~0.2ms on nodejs, mac), but we don't have to store the path so it should be more maintainable in the future.

$ node shorts-test.js  # initial Subscriptions response (gridRenderer)
original JSON.parse: 1.969ms
hardcoded remove shorts: 1.842ms
find remove shorts: 2.126ms

$ node shorts-test.js  # continuation response (gridContinuation)
original JSON.parse: 0.399ms
hardcoded remove shorts: 0.397ms
find remove shorts: 0.454ms

I'm not really able to properly test the functionality, but at least it doesn't seem to break anything on K7Lp.

Hello guys, please tell me when there will be an update with the function of hiding shorts, or now I can replace .js files in the file system via webos dev manager. But I don't know the way. Thanks for the information
