fix(stemmer): fix handling of stemmer imports

[codyzu]

hotfix for #126

• enables the TS allowJS flag so that the TS compiler copies the js files from stemmer as suggested here
• added a "smoke" test that runs a basic search after importing lyra from dist. This is an attempt to avoid errors like this in the future. I added this test to the CI also.
• removes the cjs build of the stemmer and renames the esm build to lib. Now that the typescript compiler handles importing, it should only be esm

Notes

1. The npm run script ci with coverage checks isn't actually run by the CI and notably the coverage checks are failing. Probably want to fix this in the future

If you're blocked and don't want to roll back to the previous release or wait until tonight for a new release, you can try out my fix by removing Lyra from your package.json and then npm install "codyzu/lyra#fix-stemmer-inclusion"
