ITextAnalyzer class Null safety

Interface for a text analyser class that extracts tokens from text for use in full-text search queries and indexes:

configuration is a TextAnalyzerConfiguration used by the ITextAnalyzer to tokenize source text; and
provide a tokenFilter if you want to manipulate tokens or restrict tokenization to tokens that meet criteria for either index or count; and
the tokenize function tokenizes source text using the configuration and then manipulates the output by applying tokenFilter; and
the tokenizeJson function extracts tokens from the zones in a JSON document.
