[substrait] make dependency on parquet optional #13593
Description
Is your feature request related to a problem or challenge?
The datafusion-substrait package currently depends on the datafusion crate with all default features enabled. This can force users that might want to use the substrait package to always have at least all the datafusion default features turned on.
Describe the solution you'd like
I propose that we hide parts of the datafusion-substrait crate that depend on datafusion's default feature behind some feature flags (enabled by default but that can be disabled by users)
Describe alternatives you've considered
