📎 use ignore crate for walking the file system

[ematipico]

Description

At the moment we use some in-house code for walking the file system and for matching globs to ignore the files.

While this works, we have some issues:

• we can't respect nested gitignore files during the traversal
• our glob matcher is a copy of the glob crate and it doesn't work very well with the gitignore paths
• we can't use globs in our cli

We use this crate to enhance the feature.
