BlockTree terms dictionary.
This terms dictionary organizes all terms into blocks according to shared prefix, such that
each block has enough terms, and then stores the prefix trie in memory as an FST as the index
structure. It allows you to plug in your own PostingsWriterBase
to implement the postings.
See Lucene90BlockTreeTermsWriter
for the
file format.
