Reynir

* Grammar normalized and enhanced. This may cause parse trees to be slightly different from previous versions. For example the phrase "í dag" no longer appears as a single tree node with a multi-word adverbial phrase, but instead as a temporal phrase subtree with preposition and noun nodes. Also, verb phrases are expanded into nested subtrees in a more consistent manner than before.
* Configuration files cleaned up as a consequence of the split-off of BinPackage.

* Switched to using BinPackage for vocabulary lookup
* Lots of type annotations
* Added function for simplistic lemmatization of text

* Fixed bug where a wrong version of the file `Greynir.grammar.bin` was included in the Pip package.
* Please upgrade 2.10.0 to this release as the parser won't work out-of-the-box in 2.10.0.
* That said, a fix for 2.10.0 is to install it and then delete the `src/reynir/Greynir.grammar.bin` file. It will be automatically re-generated when Greynir is next invoked.

* Grammar improvements
* Better coalescing of names, especially foreign names
