.lance files can not be symlinks: "file size is too small"

Hi.

Based on my original issue in LanceDB: https://github.com/lancedb/lancedb/issues/3197

If I download a LanceDB dataset from HuggingFace like that:

hf download --type dataset username/repo

Then in the snapshots/ subfolder of the downloaded artifacts in HuggingFace cache there will be symlinks to the actual blobs:

10010110010001001001110179af84444b9f7d4ff87ee2253b.lance@ -> ../../../../../blobs/be64f20e5723bd0a27cfdbdb41cf7d6fad94cd572a71973b717fb8340f4310c5

That's how HuggingFace stores files. But LanceDB fails to open a table with such symlinks:

error: lance error: LanceError(IO): file size is too small, /Users/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/lance-io-3.0.1/src/utils.rs:88:20  Caused by: LanceError(IO): file size is too small, /Users/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/lance-io-3.0.1/src/utils.rs:88:20    Caused by: file size is too small
 code: "GenericFailure"

Like it's literally trying to open and read a .lance symlink file as is without following it to the original source. The error originates here: https://github.com/lance-format/lance/blob/dabfb933c789b661805c36c9397d4045a1bc76ef/rust/lance-io/src/utils.rs#L86-L89

Reproduce the failure with a HuggingFace dataset containing symlinked .lance files, then inspect rust/lance-io/src/utils.rs around lines 86-89 where the reported error originates. Trace how the file is opened and verify that the dataset can be opened through the cached symlink, with regression coverage for this case if the surrounding tests provide an appropriate place.
