Publish to NPM

Publish to NPM as @blockstack/cli and update installation instructions in the Readme.

May I waltz in with the suggestion we rename the package to cli, so on npm it's @blockstack/cli ?

Edit: I was going to cite angular's cli package as an example, but they call the repo angular-cli and the package @angular/cli 🤷‍♂

@blockstack/cli sounds good to me.

I believe the reason for the weird naming of this repo is due to a previous, now deprecated package called blockstack-cli

I'd caution against putting this on NPM. This is a developers only tool, and is unsafe for use with the general public or even with developers who aren't familiar with the inner workings of Blockstack. For example, the CLI requires users to enter raw private keys for a lot of operations, and doesn't really stop you from shooting yourself in the foot if you enter the wrong private key(s) or wrong address(es), or enter private keys in the wrong order.

We are targeting developers with this tool though. The reason to publish it to NPM is to make it a little easier to install. I don't think we'll see non-developers flock to the tool by publishing it. I think the only thing we're doing here is improving our support for the tool.
