_projective plugings are available in mitsuba3.5 instead of _reparam plugins

I wrote my problem about _reparam plugins in Mitsuba3 here two days ago.

After that, I realized that I had read the stable version tutorial but installed the latest version of the library. The difference confused me. 

While _reparam is still available in the stable library whose version is 3.4.1, new plugins were introduced in the latest version 3.5.0 instead of _reparam. Those were projective plugins. In addition, the latest tutorial already described it.

Thanks to this tutorial, I solved my problem. The plugins adjust shapes to the desired ones.
