Enhancement: Make overwrite behavior of `restore` customizable
The `restore` command now supports an `--overwrite` option to configure whether
already existing files are overwritten. The overwrite behavior can be configured
using the following option values:
- `--overwrite always` (default): Always overwrites already existing files.
The `restore` command will verify the existing file content and only restore
mismatching parts to minimize downloads. Updates the metadata of all files.
- `--overwrite if-changed`: Like `always`, but speeds up the file content check
by assuming that files with matching size and modification time (mtime) are
already up to date. In case of a mismatch, the full file content is verified
like with `always`. Updates the metadata of all files.
- `--overwrite if-newer`: Like `always`, but only overwrites existing files
when the file in the snapshot has a newer modification time (mtime) than the
existing file.
- `--overwrite never`: Never overwrites existing files.
