this commit adds the ability to control the metadata fields for cairo's PDF output, using cairo_pdf_surface_set_metadata. the supported fields are title, author, subject, keywords, creator, create-date, and mod-date. properties have been added to ps-setup% (despite metadata being specific to PDF and not PostScript, but since pdf-dc% and ps-dc% both share ps-setup% to control output parameters this seemed like the most natural choice) by default, all fields are initialized to #f, except creator which is initialized to: "draw-lib (racket <version> https://racket-lang.org)"

Nit: I think "racket" should be capitalized here.

The supported fields are title, author, subject, keywords, creator, create-date, and mod-date. properties have been added to ps-setup% (despite metadata being specific to PDF and not PostScript, but since pdf-dc% and post-script-dc% both share ps-setup% to control output parameters this seemed like the easiest choice, as opposed to adding a new PDF-specific setup class)
By default, all fields are initialized to #f, except creator which is initialized to:
