* bump gopkg.in/yaml.v3
* test: cannot remove local items with cscli
* test dangling links
* test: cannot install local item with cscli
* pkg/cwhub: reorg (move) functions in files
* allow hub upgrade with local items
* data download: honor Last-Modified header
* fatal -> warning when attempting to remove a local item (allows remove --all)
* cscli...inspect -o yaml|human: rename remote_path -> path
* Correct count of removed items
Still no separate counter for the --purge option, but should be clear enough
