Support --include/--exclude

Something I did a lot with s3cmd is to grab partial directory contents over a large tree by using the following:
```
s3cmd sync --exclude '*' --include 'foo/bar/*/*/*.log'
```

Would be nice to have some way to do this. Seems like the only way to do this with s4cmd is to ls them all and try to copy them 1 by 1, but I'd have to manually compute the target path/folder for every one.

Start by locating the sync command entry point and its argument parsing, then inspect how source paths are enumerated and copied. Add include/exclude handling matching the example, and verify that only matching objects are copied to the corresponding destination paths.
