hunspell: a couple micro-optimizations to speed up dictionary loading (#12825) 
* hunspell: a couple micro-optimizations to speed up dictionary loading

1. sort by the whole entry without searching for separators first: WordStorage doesn't require strong lexicographic order (only something close to it), and the separators are anyway before any usual word characters
2. avoid stream overhead when adding an entry

Online Documentation

This README file only contains basic setup instructions. For more comprehensive documentation, visit:

Building

Basic steps:

  1. Install OpenJDK 17 or 18.
  2. Clone Lucene's git repository (or download the source distribution).
  3. Run gradle launcher script (gradlew).

We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.

See Contributing Guide for details.
