As a user the speed of vtk & csv players is to slow

[aseeland]

At the moment the speed is set to 1 second.
Adjusting the value to, e.g., 0.1 second would be easy.

However, we noted that it heavily depends on the client what data can be processed and how long it takes.
To make it faster, we would need a waiting mechanism in the Vue app that sends only new data to the client when it is ready.
