Merge for v7.2.1

[raphaelquast]

A first bugfix release for v7.2 that also brings some nice performance improvements!

🔨 Fixes

• ❗ Fix issues with aggregated datasets outside the currently visible extent
• ❗ Fix displacement of grid-labels on figure export with dpi other than the native dpi
• ❗ Fix dataset export issues with "agg" backend on some of the plot-shapes
• general performance updates for background-fetching and caching
• avoid activating the companion widget when webagg backend is active

🌳 New

• New method for raster-data aggregation: "mode" (e.g. most common value)
• The behavior of callbacks during toolbar actions can now be set via
  m.cb.<method>.set_execute_during_toolbar_action()
• New .remove() method for grid-lalbels

🌦️ Changes

• To avoid issues with "webagg" derived backends, custom "move" callbacks no longer trigger automatic updates of the plot.
  ❗ Explicitly call m.BM.update() in custom move-callbacks to trigger an update!
