osmdata 0.3.0

Breaking changes

• Remove magrittr from imports. User code relaying on reexported pipe %>%
  from osmdata must explicitly load it with library(magrittr).
  Code examples, tests and vignettes now use the pipe from base (|>) available since R 4.1 (#361)
• getbb(..., format_out = "polygon") return polygons following [https://www.ogc.org/standards/sfa/].
  Polygons are defined by a list of matrices of coordinates. The first ring defines the exterior boundary, and the following rings define holes if present.
  Also fix getbb(..., format_out = "sf_polygon") returning each (multi)polygon as a row in an sf object.
  Before, every ring was an independent polygon, even for holes or multipolygons,
  and for format_out = "sf_polygon", the features were split in a list with polygons in one item and multipolygons in another (#378).

Major changes

• Implemented c.osmdata_sc method to join osmdata_sc objects (#333)
• Depends on R >= 4.1 to use the base pipe (|>) in examples and vignettes (#371)
• Deprecate nodes_only argument in opq(). Superseded by argument osm_types (#370)
• Deprecate osmdata_sp (#372)
• Pre-prend class names osmdata_sf and osmdata rather than append; thanks to @agila5 (#373)
• Add osmadata_data.frame class to osmdata_data_frame() results (#378)
• Reimplement trim_osmdata() using sf instead of sp. Now, it checks the full geometry instead of just the points
  to determine if an object is properly contained in the bbox (only for osmdata_sf objects, osdmata_sc still wrong) (#382).

Minor changes

• Improved get_bb(..., format_out = "sf_polygon") to return full metadata
  along with geometries (#338 thanks to @RegularnaMatrica)
• Mention key-only feature requests in README (#342 thanks to @joostschouppe)
• Merge any columns in osmdata_sf() with mixed-case duplicated names (#348)
• Set encoding to UTF-8 for tags and user names (#347)
• Document the use of the input query as character strings for osmdata_*() (#349)
• Consistent NA values throughout all multi-* matrices returned by osmdata_sf() (#355)
• Fix dates and remove lubridate from imports (#360)
• Restructure class definitions of osmdata_sf() and osmdata_sc() objects (#373, #374)
• Revert added osmdata class to osmdata_data_frame() and osmdata_sc() +
  Fix docs to better represent classes accepted by trim_osmdata(), osm_poly2line() and extract function (#380)
• Use terra functions instead of raster (obsolete) in osm_elevation() (#383)
• @jmaspons is the new maintainer (#384).
