Reader was reimplemented.

Browse source 
After experiments with loading the whole file at once, and
with decoding and parsing in separate thread, lazy reader
turned to be the fastest/least memory intensive solution.
Characters are now decoded in small batches.
This improved parsing speed by ~20%.

No global state anymore. Anchors are now zero terminated strings
and TagDirectives are a simple array. Event structure was changed
to prevent size increase.
Minor fixes and improvements.
