Dear,

We are using fmpy inside a larger application where we are calling numerous times the "simulate_fmu" function with the same FMU.
More precisely, we are simulating a large period (e.g. 1 day) and each call to simulate_fmu is limited to 1 minute.

In the current implementation of FMPY, the function "supported_platforms(filename)" is called each time we call simulate_fmu.

It turns out that the total time spent in "supported_platforms" is around 26% of the total computation time (disk access is really slow)

Of course, in this particular situation, the call to the "supported_platforms" might have been done only once.

I was wondering if it was possible to skip the call to "supported_platforms" when it's not the first call for a given fmu.

Some possibilities might be:

• cache the results of supported_platforms (e.g. @lru_cache)
• skip if the user is using some set of arguments (e.g. passing a fmu_instance, initialize=False, remote_platform=None)

What do you think of such modifications?
