be able to 'cat' to Drive file from stdin

One challenge with supporting this is that if the upload fails partway through (e.g. due to a network connection issue), Drive doesn't save partial uploads. Thus, we need to either buffer the entire input in memory or on disk locally, which makes this less compelling to support versus just requiring the user to do same.

Closing this out as probably not a good idea after all given the issue of losing things with partial uploads. I have confirmed that named pipes work fine as a source for skicka to upload from; that seems to cover the use case where one is willing to risk losing the contents in exchange for not having it land on local disk.

(*) Work, except for the progress bar, which gets a bit confused since more data ends up being uploaded than originally expected, but this is just a cosmetic issue.
