Add bl module to package.json dependencies

[0xall]

Hi, I'm using ipfs-api (and I don't use js-ipfs) in my electron project.

bl is used in https://github.com/ipfs/js-ipfs-api/blob/master/src/files/cat.js#L6

but in package.json, it is not in dependencies, so error occurs when executing my electron program builded. (Of course, if I add "bl": "^2.0.1" module to package.json dependencies in my project, it works)

Can you add it to package.json?
