Version 0.5.5

• Adjusted the code used to check the version of PROJ on attach. In particular, the new approach tests only sf::sf_extSoftVersion()["proj.4"] since sf::sf_extSoftVersion()["PROJ"] might not be defined for sf < 1.0. Refs #198 and #200.
• Adjusted one of the vignettes following the changes in dplyr 1.0.8. Ref #202. Thanks @romainfrancois.
• Removed conflicting URL from package documentation spatial_edge_measures
