Suggested changes/improvements

List of changes

Here are the ones we can easily agree on:

• Add and use a cropped version of the République Française logo.
• Enlarge footer text.

Here are the ones that can be discussed (I think they make the template way more enjoyable to watch, even though they are probably a deviation from the official Inria template, which, you know, 🤷 ):

• Move logos to the right side of the title slide.
• Use a larger gradient bar on the title and new section slides.
• Enlarge progress bar.
