add configurable toggle for marking whole directories

[alxshine]

Hello again 👋 😊

This is a small PR implementing #30 , the ability to mark entire folders/directories as reviewed.

The toggleAuditedUri function will use the vscode.fs API to check if the URI in question is a directory or file, making a separate function for directories unnecessary.
This also makes adding a context menu action for the command simpler 🙂

For the behavior when encountering a directory, I added a configuration option with three modes:

• no recursion: mark the directory only
• direct children only: mark the directory and child files, no subdirectories
• full recursion: recurse into all subdirectories, toggling all files

All the best 😊

weaudit should be weAudit, or this will always return undefined.

If I understand this correctly, with recursion off you can toggle a folder as audited without toggling the contained files as audited. However, if you ever toggle any of the recursive children of this folder as audited or not audited, it will start an upward recursion of this.checkIfAllSiblingFilesAreAudited, and if any of the intermediate files are not audited, your folder will not be marked as audited anymore. Is this the desired behavior?
