[pdal] entwine error with PDAL with lasperf and no laszip

[Jim Klassen]

If PDAL is built with lasperf but without laszip then entwine gives the error:

     Exception in pool task: writers.las: Can't write LAZ output. PDAL not built with LASzip.

Tested with entwine commit cd22b9f843badcbd236999c7dd75400a7237c0df   Thu Sep 23 14:58:28 2021 -0500

The following patch "fixes" it but is less than ideal because then it requires lasperf.  Maybe using "compression": "true" would be better to let PDAL pick the implementation?  Or maybe choosing based on cmake settings?
