Just to start the discussion: I'm increasingly uncertain what to put in real-numbers versus analysis. Limits of sequences? Uniformly continuous functions?

I'm not entirely sure about this atm either. I'll think a little about it. One question that comes to mind is, what was intended by the namespace name "analysis" if not also analysis of real numbers. Perhaps a fitting starting point would be to have "convergent sequences of real numbers" in the analysis namespace, and any files about continuity of functions on real numbers there too. I'm not sure...

Perhaps we should do some planning

One of the founding principles of the agda-unimath library is to organize modules by theory rather than data structure. Although, some of our namespaces don't reflect this principle that well these days, such as lists, trees, and real-numbers. This brings me to think we might want to rebrand the real-numbers namespace to real-analysis (or something else),... to allow for future growth. To elaborate, it's not exactly clear, at least not to me, what the end goal for the study of real numbers is in and of itself, just as the elementary-number-theory namespace isn't called natural-numbers.

We turn out to need the locatedness condition to prove this is an
apartness relation, but that suffices, and we go on to prove that
apartness in the real numbers is equivalent.

Builds on some of the apartness work done in #1676 .
