+ patch out some `-f` checks to be `-e` (since `-f` is false on a block device)
+ replace `wc -c` with `blockdev --getsize64 $filename` to avoid spending 6 hours on `wc -c` before even uploading
+ `cp -a` the block device to /tmp/ with a nice filename, so google-drive-upload uses that as the GDrive filename

Wait 6 hours or so.

Then figure out the MD5 thing to validate the upload.

Thanks to https://serverfault.com/questions/6440/is-there-an-alternative-to-dev-urandom/415962

Note per https://tches.iacr.org/index.php/TCHES/article/view/8392 it may not be as secure as one might dream, but I'm OK with this given my use.

This lets me write to the disk at 128MiB/s, which is better than the ~20MiB/s I was getting when doing the naive
