Feature/#93 front end tests

[leandertolksdorf]

Current test coverage:

When running cypress tests, the coverage report gets saved into coveragefolder, we could include this in the CI output.

I added more tests for frontend-only stuff like tooltips, but I'm really struggling with tests that involve signals from the backend. See file cypress/e2e/2-indicators/line-indicators.cy.js: I tried mocking the websocket connection to send a test sample array. And the message is received at the frontend. Problems are:

• The message data is received as a string like 1, 0, 0, ... instead of an array buffer.
• Despite turning on the oscillator by clicking the start button, $osciEnabled is still false and the onmessage handler doesn't get to updating the other components.
