Hey y'all, I am new to this type of workflow, I am used to github and Pull-requests.
What is the process for adding a new extension point? With a recent foray into getting Lucene KNN into the ann-benchmarks repository, I found the need to adjust the current codec (Lucene94Codec) to allow us to adjust some values. I think the extension will only need to allow us to optionally override the `getFormat...ForField` parameters. Thanks! Ben Trent p.s. In the meantime, I am manually copying a file before calling `make` in PyLucene.
