Option to activate cache, "cache for view later", and "WiFi only" in each playlist

[sguinetti]

Describe the solution you'd like
When editing the playlist, there should be an option to activate separate caching. Also, to clear the cache for that playlist. So the user decides which playlist can have the cache or not (in playlist of live channels it is usually no but in playlist of songs or movies it is usually yes).

Also, in the case of Xtream, the series and movie lists are cached but not in live lists.

You can also add the option "View content on WiFi only" when the "Caché" option is on. This is useful for users to view offline content without compromising the mobile network data (in Latin America or Africa, the data allowance is usually 1 to 10GB per month depending on the price). This makes it more useful for roaming.

In addition, for each content (movie or series), the option "Cache for later viewing" should be added. A notification will appear when the content has been downloaded for later viewing without Internet.
