Missing dataloader variety

[ga58lar]

Currently, this repository only supports the loading of binaries in the KITTI format for scans and the PCD format for maps.
Missing:

• ply
• stl
• obj
• xyz
• las/laz

[ga58lar]

stl, obj and las/laz were not implemented. They are not my highest priority and I lack data to properly check the implementation. I would love to get some help with them.
