configuration for ProofGeneral with a Dune build of UniMath and this satellite

[rmatthes]

The provided file .dir-locals.el that configures ProofGeneral when visiting a file of this satellite is severely outdated. In particular, it still features the Rocq option -type-in-type.

More severely, it does not find the UniMath library in an installation through Dune following the organization suggested in issue #147 (with largecatmodules a sister directory of the child directory UniMath).

Here is a suggestion for a replacement of that file in case of a Dune build. This is not yet a suggestion for the organization of the GitHub repository. How to choose between old-style (Make) and Dune build? Probably, .dir-locals.el should always only be set during the installation process and not itself be part of the repository (just as for UniMath).

My suggestion tries to be a minimal modification of .dir-locals.el of UniMath. The variable unimath-topdir is calculated through the layout of issue #147, the physical mapping for largecatmodules seems to require option -R, not -Q.

The file name below has been suffixed with .txt so as to be acceptable as an attachment to this issue.
