Fix bug in pc_patch_uncompressed_from_lazperf

[elemoine]

There is a major bug in pc_patch_uncompressed_from_lazperf preventing PC_Uncompress from working on LAZ-compressed patches.

This is what we currently get when calling PC_Uncompress on a LAZ-compressed patch:

lopocs=# select pc_uncompress(points) from inrap where id=1;
ERROR:  pc_patch_uncompressed_deserialize: calculated patch data sizes don't match (0 != 16000)

The bug is that pc_patch_uncompressed_from_lazperf doesn't set datasize on the uncompressed patch. This PR fixes it.

I suggest to create a v1.1.1 release when this is merged.

@elemoine Do you think that we could add a unit test covering this issue?

Good call! I extended one of the existing lazperf unit tests, and I added a SELECT PC_Uncompress query to the lazperf SQL tests.

It's perfect, thanks @elemoine!
