Add Caching for api calls

[scampower3]

Caches the results from api calls for an hour. Caches Languages and ArtworkTypes for a day

Maybe we want an option to reset the cache

@Shadowghost added a task with no default trigger to allow for purging of the cache

I would have preferred a simple button in the settings to purge all TVdB cached data only. E.g. by adding a cancelationtoken to each entry when adding to cache.
When someone in the plug-in configuration UI, (where today only the API key is) presses the (new) clear cache button, this token would be canceled and a new token for new entries created.

.Compact() tries too free up cache in general. But I understand

Maybe we want an option to reset the cache

As an option to resetting our cached data without the need to restart the whole application.

Also I would like to have the cache time (e.g. min. Or hours only) configurable in the plug-in configuration ui, and maybe also disabled by setting the value to 0.

I do have another branch that allows for time configuration for cache. Will create the PR for that once this get merged.
