This PR adds a fix to properly handle prebuilt indexes. Randomly selected indexes from https://github.com/castorini/anserini/blob/master/docs/prebuilt-indexes.md, and all of them worked.

Example:
input: bin/run.sh io.anserini.index.IndexReaderUtils -index beir-v1.0.0-trec-covid.splade-pp-ed -stats

output:

WARNING: Using incubator modules: jdk.incubator.vector
