Include a --depth option

[muellerj]

First of all thanks for a great tool!

For renaming nested files/folders, find(1) has a -depth option which traverses the file-system in a depth-first order in order to avoid trying to rename an item in an already renamed folder:

# Rename all files and folders containing "_foo" by replacing "_foo" -> "_bar"
find . -iname _foo -depth -exec rename _foo _bar '{}' \;

Any chance of having a similar option for fd?

See: https://man7.org/linux/man-pages/man1/find.1.html#EXPRESSION

I've seen that there has been some discussion about breadth first/depth first traversal already - thank you for your consideration.
