feat: implement show & hide with pipes

[dj95]

This pull request implements the show and hide feature with remote commands via pipes. There are still some problems with the focus when having multiple tabs (zjstatus instances) open. Another issue is a race condition, when sending pipe commands too quickly, that interlock the pipes interface (which might be on zellijs side).
