Migrate to jline3

[DavyLandman]

This PR migrates the REPL to jline3, numerous issues are solved, but it also required a redesign of all the REPL classes.

This breaks some stuff, which could not be avoided. The most noticeble is that all Input&OutputStreams were removed from the evaluator. That was (in hindsight) not a good design choice, as they are about bytes, while we want to print text. This gets messy when we have to figure out which charset we should write to the stream.

Todo's:

• add back ctrl+/ support
• add back "measure time feature"
• test that the nested REPL work
• fix a few bugs around the progress bar when recovering prints
• diagnose why the progress bar got slower (in fixing it, it got 3x as fast as current main)
• fix merge conflicts with main
• add some javadocs & license headers

That's an impressive amount of work! Very nice improvements 🙂. Replacing streams with writers looks good: cleaner and less code. Regarding my comments:

• Most of them are nits
• I turned on full pedantic mode a few times to add suggestions for user-facing messages (and a few typos in comments). It's hopefully easy to batch them using the corresponding button and quickly be done with them.
• The bigger things (but non-essential) to consider, are related to moving code to more general, REPL-unspecific packages (e.g., I imagine we might want to reuse the completers in IDEs as well). See the comments for details.
• I don't have a separate comment for this, but I've been seeing some null arguments and returns occasionally, and also some checker annotations, but not consistently everywhere I think? This could be something to improve (but not necessarily in this PR).
• Some of the deeper details of the implementation were a bit hard for me to get a good feel for (e.g., sequences of jline invocations; the way in which the progress bar is manipulated). I haven't seen anything obviously wrong with it, but it's very well possible I might have missed something in those code fragments.
