Explicit line endings and encoding for MSMARCO passage on Windows

[edwinzhng]

Line endings + encoding errors in Python prevented the MSMARCO passage experiments from being replicated on Windows so this should fix it. I also re-ran the experiment again on Linux and it still worked.

Will wait for @LuKuuu to also confirm that it works for him on Windows

I'll wait for +1 from @LuKuuu before I ship.

@lintool I just tested it and it works on my device.

@LuKuuu can you add in your own replication record, per #939

Thanks!
