2.0.0-alpha.11

This release includes fixes and improvements.

Breaking changes	Addressed
Negligible	#589, #602, #607

The following changes have been made:

• An issue where AxisItemPlacer.Vertical.step misbehaved and caused exceptions for certain y ranges has been resolved.
• An issue where MarkerComponent.LabelPosition.AbovePoint and MarkerComponent.LabelPosition.AroundPoint placed the label by the lowest point rather than by the highest point for MarkerComponents highlighting multiple points has been resolved.
• CartesianChartModelProducer has been optimized to ignore Transactions that change nothing. For consistency with how series are handled, each Transaction now has a new MutableExtraStore, which is initially empty. Previously, a CartesianChartModelProducer had a single MutableExtraStore, which it didn’t clear between Transactions. In the unlikely event that you depended on this behavior, ensure that all extras are added on every Transaction.
• Selected APIs that Vico shouldn’t expose have been hidden or marked as deprecated.
