Use PDAL to pre-tile datasets for parallelization #31

This could become necessary as processing requirements increase and we transition to k8s-managed processing architecture: https://pdal.io/en/2.6.0/apps/tile.html

Side note regarding the use of LAStools in the workflow: PDAL is picky about the LAS format, so we will likely need to keep lasinfo (a free and open-source tool) in the workflow in order to standardize file headers prior to loading datasets into PDAL. The lasgrid tiling algorithm is one of the LAStools suite that requires a paid license, so in order to implement large-scale parallelization, will need to use the equivalent tool in PDAL in order to avoid licensing pitfalls. Hence this issue.
