Pull request overview

Adds support for computing and visualizing RSET (Required Safe Egress Time) maps, aligning with the ASET–RSET map concept from Issue #508.

Changes:

• Introduces compute_rset_map and RsetMethod for aggregating time-per-grid-cell from trajectory data.
• Adds plot_rset_map and exposes the new API via pedpy.__init__.
• Adds unit tests and user guide documentation for the new RSET map functionality.
