Add tape-promise into 'other'

[jprichardson]

Unlike blue-tape, tape-promise has the following benefits:

1. Doesn't explicitly depend upon tape. i.e. can directly modify tape if need be and not fixed to the tape version of blue-tape.
2. Explicitly supports async/await.
3. Has better documentation.

@jprichardson why not patch blue-tape? to me, the functionality seems so close.

1. blue-tape does support async/await (really its a babel thing)
2. docs haven't been a problem for me but a pull could fix that
3. i haven't experience an issue needing 1 (@spion has been good with pulling version bumps in), but maybe you could elaborate on why? i kinda like having tape explicitly defined as a dep so i know it works and has been tested.

[jprichardson]

1. While you're right, it doesn't explicitly (stated via Readme / include tests) support it.
2. Yes.
3. This is the most important aspect for me. I don't want it to depend upon Tape. I have a bunch of unreleased tape utilities that just decorate tape. What's cool is that people can leverage functional composition to pick/choose which they like.

e.g....

var tape = require('tape')
var tapePromise = require('tape-promise')
var tapeSomething = require('tape-something')
var compose = require('some-library-that-has-compose-maybe-lodash')

var _test = compose(tapePromise, tapeSomething)
var test = _test(tape)

test('should do something', function (t) { /** ... **/ }

fwiw, I don't think anything should explicitly state support for async/await, since that betrays a fundamental misunderstanding of what async/await is - it's nothing more than syntax sugar for nested promises, so everything and anything that works with promises supports async/await.

@ljharb that's the best description of async/await I've seen so far.

I could like to use tape-promise instead of blue-tape.

I am writing the following scripts to run ES6 test and ES6 test coverage. It is using tape directly, I could like to declare tape as devDependencies and with tape-promise.

"scripts": {
  "test": "babel-node node_modules/tape/bin/tape ./test/**/*.js",
  "test-coverage": "babel-node node_modules/isparta/bin/isparta cover node_modules/tape/bin/tape -- ./test/**/*.js"
}

@jprichardson could you check "allow edits" on the right hand side of this PR?

[jprichardson]

@ljharb done.
