simmer 3.6.3

New features:

• Show simulation progress via an optional progress callback in run() (#103).
• New "The Bank Tutorial: Part II" vignette, by Duncan Garmonsway @nacnudus (#106).
• New getters for running arrivals (#109), meant to be used inside trajectories:
  • get_name() retrieves the arrival name.
  • get_attribute() retrieves an attribute by name. The old method of retrieving them by providing a function with one argument is deprecated in favour of get_attribute(), and will be removed in version 3.7.x.
  • get_prioritization() retrieves the three prioritization values (priority, preemptible, restart) of the active arrival.
• New shortcuts for global attributes (#110): set_global() and get_global(), equivalent to set_attribute(global=TRUE) and get_attribute(global=TRUE) respectively.

Minor changes and fixes:

• Some code refactoring and performance improvements (2f4b484, ffafe1e, f16912a, fb7941b, 2783cd8).
• Use Rcpp::DataFrame instead of Rcpp::List (#104).
• Improve argument parsing and error messages (#107).
• Improve internal function make_resetable() (c596f73).
