Cleanup RoutingProfile

[sfendrich]

Problem description

RoutingProfile is a quite messy class and should be cleaned up.

Proposed solution

• Move out unrelated members (refactor: move loosly related members out of RoutingProfile #1521)
• Move compute and build methods into appropriate places (refactor: cleanup routing profile management #1951 refactor: cleanup class routing profile #1958 )
  • Matrix (4 methods)
  • Isochrones (2 methods)
  • Route
  • RoundTrip
  • Snap (https://github.com/GIScience/HeiGIT-Github-hidden-Issues/issues/64)
  • Export
• Refactor interface between ORS profiles and GH profiles
