Long: `
Produces a hash file for all the objects in the path using the hash
named. The output is in the same format as the standard
md5sum/sha1sum tool.
Run without a hash to see the list of supported hashes, eg
$ rclone hashsum
Supported hashes are:
* MD5
* SHA-1
* DropboxHash
* QuickXorHash
Then
$ rclone hashsum MD5 remote:path
