Improvement: Change behavior of -pylearn, setup-

[mdroste]

Splitting this issue out from László's earlier issue, since I view it as distinct:

"My primary Python installation lives under a conda environment (called idp, just following the Intel Distro's default). sh conda activate idp obviously did not work within Stata, as pylearn, setup did not find anything it wanted, instead, it downloaded quite a few things from pip without asking me. The latter behavior is a bit unpleasant and would be easy to fix."

I will change -pylearn, setup- to prompt the user before any installations of files. Handling the Anaconda environment issue is a separate problem dealt with in issue #3

Much delayed, the next update (in the next few days) will, among many other changes, fix this issue. Users will now be prompted whether to engage in an attempt to automatically install missing Python libraries or not.
