feat(rust): point location!() macro at Github in release builds

[wjones127]

Currently, when a user reports an error, we get locations like:

rust/lance-core/src/error.rs
/home/runner/work/lance/lance/rust/lance-core/src/error.rs
/src/lance/rust/lance-core/src/error.rs

In order to find the actual line, an engineer has to:

1. Ask the user what version they are running. If they are using a downstream package, they need to translate that version into a Lance version.
2. Open up that version in git/GitHub.
3. Find the file location.

This PR automates this by rewriting the location at compile time to the correct GitHub URL:

https://github.com/lancedb/lance/blob/v0.19.2/rust/lance-table/src/format.rs#L42

This is enabled by a feature error_location_github which is off by default. We only activate it in Python releases.
