f321fa5ad3 (array) Override to Paging...Array$range()
This is a big performance boost in array.range().get().

Without an override, each access will go through pages[page].get(...) for each get()-operation.  This adds up very quickly.  BTreeReader does a bunch of get():s on a range()'d array during traversal in the queryData... methods.

3101b74580 (index) Move to a lexicon-free index design
This is a system-wide change.  The index used to have a lexicon, mapping words to wordIds using a large in-memory hash table.   This made index-construction easier, but it
also added a fairly significant RAM penalty to both the index service and the loader.

The new design moves to 64 bit word identifiers calculated using the murmur hash of the keyword, and an index construction based on merging smaller indices.

It also became necessary half-way through to upgrade guice as its error reporting wasn't *quite* compatible with JDK20.
