lib: cache parsed source maps to reduce memory footprint

Rodrigo Muino Tomonari requested to merge github/fork/legendecas/source-map/memory-footprint into main

This also improves performance to map the stack trace when the Error.stack is accessed.

Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 2 comparisons, you can thus expect the following amount of false-positive results:
  0.10 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.02 false positives, when considering a   1% risk acceptance (**, ***),
  0.00 false positives, when considering a 0.1% risk acceptance (***)
