[chore][pkg/fileconsumer] - Move archive into separate package

[VihasMakwana]

Description

Move archive into a separate package to make code more testable and less complicated overall.
This also changes function instantiateTracker to instantiateTrackerAndArchive a little bit to initialize the archive and pass it to the tracker for writing older offsets.

This PR also drops some of the edge cases to reduce the complexity. I'll work on them later

@djaglowski can you take a look here? I've added tests and addressed the comments.

@djaglowski The testing should be good now. archive_tests is a completely separate package and it doesn't check internals. Please take a look when you can!

@djaglowski

If I'm not mistaken, when you say it's still trying to cleverly emulate them, you're referring to the calculations we perform in the tests, like i%pollsToArchive and we keep track of fingerprints as if we're doing internal tests, right?

I've taken this into consideration and reworked the approach. We now simulate a poll cycle and expect fingerprints to match. Please take a look when you can.
I've added a new test, TestArchiveRollOver, which verifies the behavior when more data is written than the archive is capable of storing. In this case, older data should be evicted.

Thanks for iterating. It's so simple even I can understand it now.

Only some nits about logging. It's good to merge from my perspective.
