Already my favourite AI SDK! Suggestion: Multiple files upload within one request!

Thanks for stopping by to let us know something could be better!

**Is your feature request related to a problem? Please describe.**
Love uploading files with this SDK, currently only a single file upload is supported 🔢 .

**Describe the solution you'd like**
It would be helpful if it also supported like multiple files to upload at once or zipped directories.

**Describe alternatives you've considered**
technical alternative solution: array of files support for the method :
`client.files.upload(path="a11.txt")` into `client.files.upload(paths=["a11.txt","a12.txt","a13.txt"])`

Anyways, already enjoying this SDK so much
