[pdal] PDAL Extraction / Un-compression

[Andrew Bell]

SLPK files are really gzip files inside an uncompressed zip archive.  The
current code extracts the gzip file from the zip archive by writing it to a
temporary location.  You should be able to use the TMP or TEMP environment
variable to set the path as you choose.

In the future it may be possible to eliminate the temporary file creation,
but the current behavior of the code is as described above.

Hope that helps,
