Add fan rpm and fps

[matteo1096]

Hello everyone, first of all thanks for all the work you do, I created this theme following all your guides, once complete I will upload it available to anyone who wants to use it. I use a turzx 3.5" screen.

This above is the preview of my theme, I wanted to ask if it was possible and if someone can help me finish it, I would like to be able, where I circled in the preview image, to put the % of fan usage on the left and the number of RPM on the right or viceversa, rpm in radial and percentage as text, is this possible?
As for the fps I have an nVidia RTX 4070 super and the debug tells me that the video card fps is not supported yet, so when I run the program in the output on the screen an empty space appears. I read other discussion where you say fps are only avaiable for amd gpus, so really there is no way to have them? Can't rtss be integrated into librehardwaremonitor and then show the data in the theme?
These are just ideas, I don't know if they are feasible things for that I want the advice of you more experienced.
I thank everyone in advance!
