A new minor release that brings a lot of fixes and some nice new functionalities!

🌳 New

There is a new convenience method to quickly update the properties of the frame of a map:
- set boundary line properties and use rounded corners for map boundaries
- set background patch color

m = Maps()
m.set_frame(rounded=0.5, edgecolor="r", linewidth=2, facecolor="0.5")

m.add_annotation() and m.add_marker() now support the "update" kwarg to override update triggers
(useful to avoid unnecessary updates if multiple dynamic annotations/markers are added in a callback)
m.add_gdf() now supports the "permanent" kwarg to control if artists are updated on each event
or added as background-artists
The 🚀 Contribution guide contains a new chapter on how to build the docs!

🌦️ Changes

(use m.show_layer(m.layer) to show the layer of a selected Maps object!)
Activating the AnnotationEditor now clears all currently visible temporary artists and disables all callbacks
