patch: stabilised stack parsing algorithm

currently featured:

- near perfect non-regep path extract (non supported edge case yet to be found),
- support for unix, linux, mixed, protocol, win paths
- resistance to noise (multiple non user path, eg native:1:1, <anonymous>:1:1)
- minimal footprint

chore: pkg.json fix and mention plus readme

barebone prototype

current features:
- precise stack line parsing
- reliable extraction of file, line, column
- path support:
  • Unix-like paths
  • Windows-style paths
- protocol support:
  • http://
  • file://
  • node:internal
