promwrap

Wraps modules, and other objects, full of callback functions in promises.

``javascript
let fun = (x, cb) => cb(null, x)
let _module = {fun, prop: 'test'}

test('test basics', async t => {
t.plan(4)
let mod = promwrap(_module)
t.same(mod.prop, 'test')
t.same(mod.prop, 'test')
t.same(await mod.fun('test1'), 'test1')
t.same(await promwrap(fun)('test2'), 'test2')
})

Promisify all function properties of value. If value is a Function,
it will be promisified instead. Members of Object.prototype are not
promisified.

Returns value, wrapped by a Proxy.

- If exclude is supplied, do not promisify this prop/list of props.
- If excludeMain is truthy and value is a Function, treat value like a
plain Object and promisify its props instead of value itself. In
addition, members of Function.prototype will not be promisified.
- If own is truthy, only promisify the Object's "own" (in the
Object.hasOwnProperty()` sense) props
