build fail when including cfb 1.0.3

[jdeviney]

I'm trying to import and use xlsx which depends on cfb. When I build my angular 5 project I get the following error:

ERROR in node_modules/cfb/types/index.d.ts(38,24): error TS2304: Cannot find name 'Buffer'. src/app/components/purchase-order/register/register.component.ts(98,12): error TS2304: Cannot find name 'Buffer'.

I have no problem resolving this base type in my main project but it fails inside of cfb. Am I using an incompatible module or is this possibly a bug in cfb? My package.json file contents:

We just pushed 1.0.4 with a fixed type definition -- you should be able to npm rm xlsx and npm i xlsx again to pick up the latest version of the dependency.
