Remove 'Example' target

[apascual]

Hi,

Swift Package Manager has issues when two dependencies contain the same target name (https://forums.swift.org/t/multiple-target-issue-with-spm/16696).

The targets should be named properly to avoid conflicts with other libraries.

I haven't jumped into this issue, can we confirm that this is still an issue with SPM?

I can confirm this is still an issue with Swift 5.5 (Xcode 13.2.1), when trying to use Komondor.

error: multiple targets named 'Example' in: 'packageconfig', 'swifter'

I'll make a PR during the next week.
