Find a common root subdirectory for a set of input paths. Optionally, concatenate the paths which share this common root subdirectory to a new to a new common root.

For example, given:

/my/my/common/path/a.png
/my/my/common/path/b.png
/my/my/uncommon/path/c.png

It finds the common root: /my/my, and the unrooted branches:

common/path/a.png
common/path/b.png
uncommon/path/c.png

If you decide to concatenate a new root directory /new, it will output:

/new/common/path/a.png
/new/common/path/b.png
/new/uncommon/path/c.png
