Promise support

[Richienb]

It would be useful if nice-try supported promises:

const niceTry = require('nice-try')

const result = await niceTry.promise(async () => {...})

Implementation:

module.exports.promise = async function(fn) {

	try { return await fn() } catch (e) {}

}

Maybe this should be PR instead of an issue; you already have the implementation.
