Version 2.4.0

• Added test for foreign sentences, i.e. sentences where less than 60% of the words are found in BÍN (or resolved by the composite word algorithm). Such sentences are now marked by an error code instead of being parsed.
• More flexibility in specifying the maximum length of sentences to be parsed. The (overridable) default is now a maximum of 90 tokens in a sentence.
• Added and enhanced functions for generating lemmas from parsed sentences. New properties include _Sentence.lemmas_and_cats and _Sentence.categories, and the method Greynir.parse_tokens() has been added.
• Grammar and vocabulary improvements.
• Better handling of abbreviations and multi-word prepositions.
• Improved type annotations in the main Greynir API.
• Added tests.
• New features documented and examples added.
