Goals ⚽

The goal of this PR is to remove deprecation tools and reduce the targets. We are not using Cocoapods anymore neither UIKit. In addition, we will fully adopt Swift Concurrency in the future so it doesn't make sense to expand too much in the reactive solutions like Combine.

Backwards-compatibility:

From The new version and upwards:

• There will be only one target for Combine (FueledUtilsCombine).
• No Cocoapods Support
• No UIKit Helpers.

Implementation Details 🚧

• Use one Combine target (FueledUtilsCombine) instead of FueledUtilsReactiveCommon & FueledUtilsCombineOperators.
• Remove Cocoapods support and related files.
• Remove UIKit helpers files.
• Add two test targets instead of a big one that contains everything.

Testing Details 🔍

• I removed Pods from testing.
• We have two separate targets for testing, FueledUtilsCoreTests and FueledUtilsCombineTests.
