PLAYA 0.2.x

Fix ToUnicode CMaps for CID fonts (file bug against pdfminer)
decode_text is remarkably slow
render_char and render_string are also quite slow
add something inbetween chars and full bbox for TextObject (what do you actually need for heuristic or model-based extraction? probably just adv?)
remove the rest of the meaningless abuses of cast
document how to transform bbox attributes on StructElement, Destination, etc (but you should just use "default" space)
deprecate LayoutDict

make the structure tree lazy
support ExtGState (submit PR to pdfminer)
better API for document outline, destinations, links, etc
test coverage and more test coverage
support matching ActualText to text objects when possible
- if the text object is a single MCS (LibreOffice will do this)
