Add a new 'flooding_lib.tools.pyramids' app that can store grids and animations as gislib pyramids.
Add a function to add rasters, simple tests
Cleanups
WIP on generating pyramids automatically
Presentation layer for Pyramids
Animation model
Also generate pyramids for animations
Save animations as geotiffs, show them using the old machinery
Hover over pyramids works
Add hover handler for animations
Make colormaps, max values dynamic
Add maxvalue field to animations, represents maximum value over all the frames
WIP on select a legend dynamically
Making automatic switching of colormap and maxvalue work
Add configurable colormaps, and default colormaps / maxvalues per presentationtype
Everything below 1cm is NODATA; delete the pyramid files when a Pyramid instance is deleted.
Don't copy pgns anymore for animation presentation layers
Create a pyramid presentation type for each current grid presentationtype
Only generate presentationlayers if the results exist; don't delete entire results just because a raster or animation is deleted
Also generate 'correct' arrival time and time of max level grids when creating animations
