Doesn't work in IE11

[Michael Amos]

Not sure what you're targeting as far as browser support but the following line blows up in IE11:

hex-to-rgba/src/index.js

Line 1 in 6987950

 const removeHash = hex => (hex.startsWith('#') ? hex.slice(1) : hex); 

This is because String.prototype.startsWith isn't supported as shown in this table: http://kangax.github.io/compat-table/es6/#test-String.prototype.startsWith

Opened PR #9 to address this issue.

Thanks for pointing this out - I've only used this in projects with polyfills on the client side, so I never encountered the issue myself.
