fix: check ole storage content to differentiate filetypes (#3581 )

### Summary

Updates the file detection logic for OLE files to check the storage
content of the file to more reliable differentiate between DOC, PPT, XLS
and MSG files. This corrects a bug that caused file type detection to be
incorrect in cases where the `filetype` library guessed and incorrect
MIME type, such as `'application/vnd.ms-excel'` for a `.msg` file.

As part of this work, the `"msg"` extra was removed because the
`python-oxmsg` package is now a base dependency.

### Testing

Using a test `.msg` file that returns `'application/vnd.ms-excel'` from
`filetype.guess_mime`.

```python
from unstructured.file_utils.filetype import detect_filetype

filename = "test-file.msg"
detect_filetype(filename=filename) # result should be FileType.MSG
```
