Add loading time information

[Myzel394]

What does this PR do?

To see the durations it took each engine to load, this PR adds this information to the sidebar.
This is still a WIP, I opened this draft to see whether this is heading into the right direction :D.

Why is this change important?

All major search engines show their duration. Having easy access also makes it more transparent to users what engine may be causing long loading times.

How to test this PR locally?

Here are screenshots, remember that this is still a draft and I will definitely need to adjust the styling, tags etc:

2 decimals are probably more than enough :)

And in my opinion, this should be hidden at all by default and expandable with an arrow at the right, next to "Number of results: ...".

Hehe yeah so I didn't bother to change it to a human readable format yet; We could either show it in seconds like: "2.45 seconds", "0.67 seconds" or in milliseconds like: "2450 milliseconds", "670 milliseconds" - I personally prefer seconds.

how about we format it like this:

"Number of results: 2,450,000; Took 2.45 seconds" - 2.45 seconds being the longest engine and this whole paragraph is expandable then?

Same, seconds are more user friendly.

That sounds good to me 👍

Alright, so that's what it looks like now:

although it feels too light for me; search engines usually show this beneath the input. However, in this case I don't know where to reasonably put the detailed list of engines
