example usage:

las2las14 -i ..\data\TO_core_last_zoom.laz -o to_14.las
las2las14 -i ..\data\TO_core_last_zoom.laz -o to_14_6.las -six
las2las14 -i ..\data\TO_core_last_zoom.laz -o to_14_7.las -seven
las2las14 -i ..\data\TO_core_last_zoom.laz -o to_14_8.las -eight
las2las14 -i ..\data\TO_core_last_zoom.laz -o to_14_9.las -nine
las2las14 -i ..\data\TO_core_last_zoom.laz -o to_14_A.las -ten

the flags '-six' to '-ten' indicate that the old point types 0 to 5 of the input should
be upconverted to the new point types 6 to 10. then the LAS 1.4 file will no longer
be compatible with earlier versions of LAS (i.e. readable by older, forward compatible
LAS readers).

examples:

C:\lastools\bin>las2las14  -i ..\data\TO_core_last_zoom.laz -o to_14.las
writing 213093 points of type 1 to LAS 1.4 took 0.515 secs.
