* fix: Exit gracefully instead of panicking when trying to use features
* removed an unnecessary empty line
* Added logging of any errors encountered writing to stderr.
* only add regular files to path list
This fixes multiple issues. Before this commit, a directory with
a known file extension in its name would be added to the list of
"files" to open and read from. Another issue occurred with broken
symbolic links being added to the files list.
* add test to ensure directories not treated as file
* replace `unwrap()` with `rs_error!`
