patterns: Added a few voxel model patterns (#74)

* patterns: added a few voxel model patterns

* patterns: updated qbcl

according to https://gist.github.com/tostc/7f049207a2e5a7ccb714499702b5e2fd

* readme: added new voxel format petterns to the readme

* tests: added vxl test file

* ccvxl: updated two fields
