PathManager making too long temp filenames
Currently the TQPathManager includes the destination in the temp file name which adds significantly to the length of that file name. When the original fn is already fairly long this can cause the (temp) file name to exceed 256 characters and the file cannot be opened/created.
Maybe we could shorten things here a bit, e.g., by hashing the long (temp) file name or only including a unique ID?
A second issue (including it here as it should be a trivial fix): it seems when copying local file to their destination the PathMan doesn't ensure the existence of the target directory yet (solution is likely a one-liner when using this: https://atlas-caf.web.cern.ch/TQUtils.html#TQUtils:ensureDirectoryForFile)
