UI/UX using rich: progress bar, logging

We could add some visual feedback while compiling many extensions. The rich library is particularly good. See the progress bar example. I think we can add them here: https://foss.heptapod.net/fluiddyn/transonic/-/blob/48c5fd9224665d88fba90586edca91309f21961b/transonic/compiler.py#L77-106. Isn't it

Note that rich can replace the colorlog package as shown here.
