v1.37.0

Added

• Add plotly_legendclick and plotly_legenddoubleclick events [#2581]
• Add Swahili (sw) locale [#2526]

Changed

• Improve cartesian trace update and removal by using more d3-iomatic patterns.
  This results in some performance improvements during redraws [#2574]
• Our internal Lib.nestedProperty no longer prunes empty containers in
  gd.data, gd.layout, gd._fullData and gd._fulllayout.
  We made this change to clean up some of the Plotly.react internals.
  This also lead to a slight performance boost [#2577]
