chore(r/sedonadb): Update savvy to v0.9

[yutannihilation]

Close #394, close #393

While the update itself is almost no change in Rust code (so, this update is totally optional), the R wrapper is changed a bit. This pull request updates it manually by the following steps:

# If not installed yet.
install.packages(
  "savvy",
  repos = c("https://yutannihilation.r-universe.dev", "https://cloud.r-project.org")
)

# Download the latest savvy CLI
savvy::download_savvy_cli()

# Update the R wrapper files
savvy::savvy_update()

# Generate documents and NAMESPACE
devtools::document()

Thank you!

I'm not sure if there's a good way to embed the license file, but historically I've had to manually add it back in whenever I update the R rust code (perhaps you ran into that here too).

Yeah, I did the same. Maybe I should make savvy support the license header, but manual edit is enough for now...
