infer the future from the past - store results in a database

**Is your feature request related to a problem? Please describe.**
The main problem on pluto.tv is the extreme limitation of the EPG - we can hardly see half a day into the **future**.

**Describe the solution you'd like**
Not really a "solution", but if we had knowledge about a longer timespan in the **past** then we can infer the shape of their rotation.

And then our educated guesses can help us a little bit, for what to expect in the **future**.

**Describe alternatives you've considered**
The idea is to ... **feed the results of every call, every search, every filtering into a database.**

Either just the filtered subselection - or as a brute force approach, the whole API answer.

Beginning, it could simply be a flat file. E.g. columns 2,3,4 are always time,month,day - so that stays readable later.

**Additional context**
Beware that every API answer consists of approx 3000 episodes. It might be better to just store the results AFTER the filtering.
