Not a supported format error for 32f wav

[ismay]

With the latest version I'm getting a Not a supported format. error when attempting to read a 32f, mono wav.

Build log here
Code that's failing here
Code for failing test here

I didn't see any tests for reading 32f wavs, is this currently supposed to be functional?

The wav file was generated with wavefile 5 with this script:

const fs = require('fs');
const path = require('path');
const { fromImage, toWav } = require('./lib');

const imagePath = path.join(__dirname, 'test', 'fixtures', 'image-to-float', 'input.png');
const imageBuffer = fs.readFileSync(imagePath);

fromImage(imageBuffer).then(floats => toWav(floats)).then(wavBuffer => {
  fs.writeFileSync(path.join(__dirname, 'input.wav'), wavBuffer)
});

My mistake, I forgot to call toBuffer(). Sorry!
