step_size not passed on to energym by integration

[rdnfn]

Problem

There appears to be a mismatch between the user-defined step size and the actual step size of the simulation. The plot below shows the solar radiation, and indicates that a day is about 480 steps (step_size 3min), as opposed to the 96 steps that the configured step_size of 15min would mean.

Potential Solution

As far as I can tell the step_size parameter is not actually passed on to the Energym env making command, thus it defaults to another step_size. Creating the relevant logic should be sufficient to fix this.
