The current implementations of file_download and file_upload are relatively brittle, as they rely on the text-based serial interface to send and receive content.

WebREPL seems to implement a native file upload/download mechanism over websocket that also works for binary files.

However, the implementation of the file transfer protocol is pretty much buried in the JavaScript of the page itself.

Reverse engineer the protocol and implement a robust mechanism for file transfer.
