Please add file-finder

[vindarel]

file-finder is a rapid file search and manipulation library.

https://github.com/lisp-maintainers/file-finder

Example:

(finder "fil" (extension= "lisp"))

=> recursively find all files whose path name contains "fil" and have a ".lisp" extension.

It excludes hidden files and directories by default, as well as common directories (node_modules).

It is a simplified fork of https://gitlab.com/ambrevar/fof/

Thank you
