Load simulations done with pfft/p3dfft without these libraries
It should of course be possible to load simulations done with pfft/p3dfft without these libraries.
Unfortunately there is no argument in `load_sim_for_plot` and `load_state_phys_file` to do that (as experienced by @jreneuve).
It seems to me that `load_sim_for_plot` and `load_state_phys_file` could set `params.oper.type_fft` to `"defaut"` by default.
However, I also think we should add an argument `overwrite_params` to these 2 functions to load simulations with modified parameters.
@jreneuve and @avmo, I would be happy to know your point of view.
