Feat: Add automatic tests for base use cases

[mrkeuz]

Problematic

Currently, release cycle not fast enough because we should manually run base test cases.
So many ideas and hypotheses came, but for implement every next you will need tests it manually.
I want will all works best all possible. And for this need fully testing system.
Unit + Integration with real player (as protocol may have I.e. corner cases and regressions)

Solution

It requires covering base use cases. And more complex scenarios which users expect.
I.e. #5 need complex tests on two computers/VM's + matrix Lin+Win and vice versa

Plus different versions of vlcsync, OS, bruh... )
