ggsql 0.5.2

This release updates the bundled ggsql Rust library to 0.5.2 and moves display and export over to the new native writers, with breaking changes to ggsql_widget() and the writer knitr chunk option:

• The bundled ggsql Rust library has been updated to 0.5.2, bringing the new native hephaestus-based writers.
• New writers: svg_writer(), pdf_writer(), and hep_writer(), rendered natively by ggsql without any JavaScript round-trip. vegalite_writer() is deprecated and will be removed in a future release.
• ggsql_save() now exports SVG and PDF directly through the native writers, and also supports .hep output. PNG export converts the native SVG output with rsvg. The V8 package is no longer needed for rendering.
• Display has moved from Vega-Lite to a .hep plot document rendered in the browser by the hephaestus SVG renderer compiled to WebAssembly:
  • ggsql_widget() now takes a spec as its only required argument (ggsql_widget(spec)) and produces a ggsql_hep htmlwidget that re-lays out the plot as its container changes size, with fonts bundled.
  • The min_width argument has been removed; the new renderer re-layouts rather than scales, so narrow containers get a properly laid out plot.
  • The writer knitr chunk option now accepts "hep" (default for HTML output), "svg", "pdf" (default for LaTeX output), and "png". The old "vegalite"/"vegalite_svg"/"vegalite_png" values still work with a deprecation warning.
• ggsql_widget() is now exported as the public way to build an htmlwidget from a spec.
• Now works correctly on Windows ARM64 (#15)

ggsql 0.3.3

• Declare correct Rust version dependency at 1.86
• Bump ggsql dependency to 0.3.3
• Patch ggsql dependency to work with Rust 1.86 so it works on CRAN build machine

ggsql 0.3.2

• The vendored Rust crate archive is no longer shipped inside the source tarball. It is downloaded at install time from the matching GitHub Release (vendor.tar.xz) and verified against a sidecar SHA256. Override with GGSQL_VENDOR_TARBALL, GGSQL_VENDOR_URL, or NOT_CRAN.

ggsql 0.3.1

• Initial CRAN submission.
