v0.2.0

Added

• [interface] [engine] 3d plot & scatter.
• [interface] [engine] 3d plot support: zlim(), zlabel().
• [interface] [engine] engine-specific parameters via kwargs: plot(), scatter(), legend().

Changed

• [engine.matplot] legend outside the plot (same as plotly legend).
• [engine.matplot] change from tight_layout to constrained for more predictable behavior.
• [engine.matplot] axis and frame disabled for imshow().
• [engine.plotly5] fixed size of legend's markers.

Fixed

• [engine.plotly5] prevent name truncation (ellipsis) of a trace when hovering over.
