[pgpointcloud] GHT compression

[Lars]

Eric: Thanks for the feedback.

Just got an email from Paul Ramsey who was involved with libght implementation. He says;

"No, GHT is dead. It's a bad fit for the db environment. It *might*
have some use as a file format, but even though I feel like a patched
laszip could probably do just as well."

kind regards, Lars

I've never used GHT myself. What I know though is this major bug when
GHT is used: https://github.com/pgpointcloud/pointcloud/issues/196. I
haven't had the time to look into this bug.
