promise

From time to time i see ppl using data instead of body which is wrong.
happened just recently in node-fetch/node-fetch#481 (comment)

how do you feel about adding a little warning message that can only appear once. (kinda like node reports that you are using experimental apis)

if ('data' in bodyInit && notWarned) {
  console.warn('use body i

Summary of Problem

Not able to open port with stopbits as 1.5

I am currently building a desktop client using electron, where the COM port receives data correctly for values: baudRate: 2400, dataBits: 7, stopBits: 1.5, parity: 'none'

I found from the node-serialport documentation, stopBits Must be one of these: 1 or 2. But, should 1.5 be supported as well? especially for old & slow

From what I can tell, the ApiResponse objects can never have an undefined config.

Config is defined as optional here:
https://github.com/infinitered/apisauce/blob/master/apisauce.d.ts#L44
But is required here:
