Add space between brace option

[vjpr]

When using collapse-preserve-inline and destructuring:-

// Currently
const { TestHelper } = require('../app/TestHelper')

// Desired
const {TestHelper} = require('../app/TestHelper')

But...functions on a single line I prefer to keep spaces in braces.

function foo() { console.log('foo') }

• We should distinguish between object braces and function braces, and allow a "space inside braces" option to be configured separately for each.

This is not implemented at this time. Any help appreciated.
