CRAN version 0.1.9

Major changes:

• New function opq_around to query features within a specified radius around a defined location; thanks to @barryrowlingson via #199 and
  @maellecoursonnais via #238
• New vignette on splitting large queries thanks to @Machin6 (via #262)

Minor changes:

• New dependency on reproj package, so that trim_osmdata() can be applied to re-projected coordinates.
