test: add test for issue 1054 (newer fsspec failing to parse files with colons in name) (#1055)

* add test for issue 1054

* additional test

* make sure fsspec fix works

* try new test in older fsspec version (need to test windows)

* skip test in windows due to colons in name

* add explicit object-path split with open

* revert use fsspec fork in ci
