Issues with webworkify + browserify #44

I'm hitting a wall with webworkify 1.5.0 when using it with browserify 16.2.2.
This error pops up on build and the app becomes unusable

TypeError: Cannot convert undefined or null to object
[1]     at Function.keys (<anonymous>)
[1]     at module.exports (/mnt/c/Users/Benjy/Documents/Github Stuff/cryptovoxels/node_modules/webworkify/index.js:9:28)

I thought my issue was a bit similar to #43 so I tried what legubiao did, but no luck.
