Array brackets within keys sometimes mess up processing

[Aaronius]

Hi! Thanks for the great library. I'm noticing an issue when array brackets are within keys. For example:

const data = {
  "a[]b": "c"
};

dot.forEach(data, 'a[]b', () => {
  console.log('match found');
})

I would expect "match found" to be logged, but it's not. It seems that dot-wild isn't treating the brackets in some special way when it should be treating it as regular characters within the key.
