Visualisation of point clouds with different colour palette

[spono]

Just for visualisation purposes, a potential improvement of #275 could be to have the possibility to plot together two point clouds with different colour palettes.

I think something like:

las1 # classified scene without trees
las2 # only trees
plot(las1, color = "Classification") # mainly to distinguish ground VS man made objects (buildings, power lines, etc)
plot(las2, add=TRUE) # add the trees coloured according to Z

This is a fair feature request that can probably be done within a very short term.

[Jean-Romain]

library(lidR) # >= v3.0.0
las = readLAS("building_WilliamsAZ_Urban_normalized.las")
nonveg = filter_poi(las, Classification != LASHIGHVEGETATION)
veg = filter_poi(las, Classification == LASHIGHVEGETATION)

# Regular plot
plot(las, color = "Classification")

# Two point cloud with different palettes
x = plot(nonveg, color = "Classification")
plot(veg, add = x)

amazing!
