Shrink package size

[TimDaub]

The driver's current package sizes are - though uglified - almost 500KB.

That's too much. I'm suspecting that we're injecting a bit to many dependencies or are using a bit to many babel shims that have to get included in the uglified bundle.

The goal here is the following:

• see what options we have to shrink the bundle
• aim for realistic target
• play with uglify options to see if package size can be decreased
• see if there is dependencies that could now be replaced with native browser functionality
• etc.

I'm sure there's lots of tutorials on the web to shrink package sizes.

Driver size: 510 kB

Biggest included packages:
./node_modules/five-bells-condition/dist/index.js 396 kB {0} [built]
./node_modules/node-libs-browser/node_modules/buffer/index.js 48.6 kB {0} [built]

To get output of all modules included in build execute webpack with --display-modules parameter.

Seen @jernejpregelj comment, I close this issue and I create the same issue but for the js-crypto-conditions repository as is the one causing a big size of the JS BigchainDB Driver
