GoingElectric: Add option to combine the filters by network and payment method with an "AND" condition instead of "OR"

As mentioned in #249 in discussion with @Ixam97, this can only be implemented as a local filter.

• UI idea 1: Extra checkbox next to one of the filters to choose whether to use AND or OR
• UI idea 2: Leave functionality of the current "Network" filter as-is (OR), and add a new filter "Exclude networks" which uses AND. Maybe "Network" should then be renamed to "Include networks". This seems kind of intuitive to me.

However, as a first step, I think we should implement #136 to make the current behavior clear to the user.

I'm not entirely sure if I understand the proposed change correctly, so I can't say if what I noticed today aligns with it.
I tried setting up a filter profile that only shows chargers that belong to a specific network/operator (in my case "EWE/SWB"), but since I have to select at least one payment method/charging plan so any chargers get listed, I always get all chargers that are compatible with the charging plan and the selected network gets more or less ignored.

So, any option to enforce that the network selection is obeyed (or, to word it differently, that roaming partners are ignored) would be really helpful.

@NiyaShy You can achieve this by simply not using the payment method filter (i.e., selecting all payment methods).

Worked, thanks. Not very intuitive though, so I understand why you want to prioritize #136 😉
Sorry for "hijacking" the issue then, and thanks for your great work on the app.
