This pull request adds support for the [PASE](PostgreSQL Approximate Search Extension) algorithm to the ANN-Benchmarks framework.
What's included:
ann_benchmarks/algorithms/pase/module.py: Python wrapper for PASEDockerfile: Container for benchmarking PASEconfig.yml: Hyperparameters and settings for benchmark runsAbout PASE:
PASE is a high-performance vector search index extension that is developed for PostgreSQL. PASE uses two well-developed, stable, and efficient approximate nearest neighbor (ANN) search algorithms, IVFFlat and HNSW, to query vectors from PostgreSQL databases at a high speed. PASE does not support the extraction or output of feature vectors. You must retrieve the feature vectors of the entities that you want to query. PASE only implements a similarity search among a large number of vectors that are identified based on the retrieved feature vectors

Looking forward to feedback. Let me know if there's anything else you'd like me to test or adjust. Thanks!
