Encoding in util.py

[Allain18]

When calling apio upload on Windows 10 for a TinyFPGA-BX, I get a UnicodeDecodeError, but the upload is still a success.

With the correct encoding, I get the loading bar during upload.

Tested only with a TinyFPGA-BX on Windows 10 and Linux.

Without the fix

Seems to be a bug with my venv, I created a new venv and it works now.

Update, it seems to be a problem with the terminal in VSCode, feel free to merge or close
