Generate a Datafile with command like data init

[btc]

Many package managers provide commands to generate blank manifests. This would be nice to have.

Examples:

# npm: Interactively create a package.json file
npm init

# Ruby: generate a blank Gemfile
$ bundle init

Currently this is covered with data pack make, which is a plumbing command underneath data publish.

data publish just calls:

• data pack make
• data pack upload
• data pack publish

See data pack help.
(I think data pack make -> data pack init.)

It may be the case that data publish creates more confusion than it saves. The idea behind it is to have an (admittedly aggressive) "one command to publish."
