Add Phosphor Icon lib

[olegvakulenko]

I want to ask.
Do the authors of the project have the opportunity to add support for another free icon library Phosphor?

https://phosphoricons.com/

As an advantage over Font Awesome, it is possible to note the presence of 6 different styles that are completely available for free. The use is completely similar.
If necessary, I can prepare a PR for a list of icons by analogy with other libraries. Unfortunately, I did not manage to quickly figure out where exactly I needed to make changes in the components.
