Invalid test files in trunk/test/data

[mloskot]

The LAS files we use in tests do not consist of georeferencing information which is mandatory. So, these files are invalid because do not conform to the ASPRS LAS specification.

browser:trunk/test/data/srs.las is one file that does have georeferencing information. Since most of the LAS files do not include this, I don't know that this ticket can do much other than to remind us that most of the LAS writers in the world don't write valid LAS files (including ours, at this time) :)

browser:trunk/test/data/srs_utm17.las is a 1.1 file that contains a full UTM Zone 17 geotiff specification that was written with the newly implemented geotiff key writing support.

As far all other files in the LAS ecosystem not writing geotiff keys, there's not much we can do about that...
