What feature or improvement would you like to see?

The driver manager doesn't have to necessarily require the same version that the datafusion driver requires (due to datafusion's specific arrow version requirements).

So I propose a more flexible range of versions in the workspace Cargo.toml:

-version = "54.1.0"
+version = ">=53.1.0, <55",

This allows applications that are still using Arrow 53 to use the driver manager without introducing another version of Arrow to the dependency tree.
