fix file sizes not appearing when filename too long (#78)

* fix file sizes not appearing when filename too long

* refactor previewing code

 - event.rs is moved out of utils as its an integral part of the codebase
 - load_child.rs has been replaced with preview module
 - moved previewing logic inside run.rs instead of spreading it across multiple
 commands

* revert tui_dirlist_detailed to use MIN_LEFT_LABEL_WIDTH

 - add previewing loading trigger to mouse input as well

* fix: right label disappears (#79)
