Function to_display_path 

pub fn to_display_path(
    loc: &S3Location,
    profile_display_name: &str,
) -> DisplayPath

Build a DisplayPath from an S3Location.

The profile display name is passed in as a &str because it lives in the profile store, not in S3Location. Segments are split on / and empty strings are filtered out so trailing slashes and double-slashes do not produce empty breadcrumb items.
