Fixes, static version, more examples

FIXES

• Whole pie piece pie charts will not honor oPadding and slices will not end up with negative size if reduced by oPadding.
• Annotation handling updates other properties even if it's not required for the annotations to change, also support a dataVersion flag in bump type annotation layouts so you can tell it to re-fire the layout
• Curly arc brackets were incorrectly calculating the largeArcFlag resulting in cool but terrible arcs

FEATURES

• unpkg support from @tmcw!
• Honor new extents in brushes to allow programmatic brush extents (feature shown in the Swarm Brush, Line Brush and Minimap examples)
