Could be factorized in parent method

this is same part with foward, could you factorize ?

LASLoader will be called by the worker, so we need to limite the dependances, thus it would be counter-productive.

it's fist transformation to move on local space
There isn't the rotation

Factorize with the line 154

I don't really see the benefit of doing so, moreover when we have the idea (in the futur) to allows proj4.defs as crs. In this cas it will simplifed the options as passing only the crs.

could you the same signature and this
setRootBboxFromArray(bounds)

If i understand you, you want to add another methode, with a different signature. But currently this function is call 4 times, if we add a 2nd one, both will be called 2 times, won't it be unfactorizing some code ?

The aim of the PR is to allow projection of dataPointCloud in a view crs different than the source crs.
For the projection we use proj4.
There is two main parts in this PR:
Instead of doing pure projection we add after the projection, an transformation of data in a local system orienté in the direction of the data and z orthogonal.
Other minor change:
A 'elevation' propertie was also added to replace the z data (that is not an elevation)
