Split up EOS and ETH dependencies about scatter-js

[liamcurry]

Well if the goal is to support a ton of different blockchains and EOS sidechains then it might be worth considering using lerna. This is how Babel/React/Jest manage their packages and it allows for developers to pick and choose components:

• https://github.com/babel/babel/tree/master/packages
• https://github.com/facebook/react/tree/master/packages
• https://github.com/facebook/jest/tree/master/packages

Some example Scatter packages:

packages/
    scatter-core/
    scatter-plugin-bitshares/
    scatter-plugin-eos/
    scatter-plugin-ethereum/
    scatter-plugin-steem/
    scatter-plugin-telos/

Also are you sure it's necessary to export the .cjs/.esm/.min.js files? Seems like all that's needed is for Babel to transpile the src/ directory to the dist/ directory and in package.json set "main": "dist/scatter.js". Minification and bundling should be handled by developers IMO. I have an old proof of concept of how this + Lerna would work here if you'd like to take a look: https://github.com/liamcurry/gql/tree/master/packages

Indeed this is something I've considered and even talked about with a few others already. It wouldn't be quite as simple as adding a requirement in the constructor or something like that though as those dependencies would be bundled in the package regardless ( i'd assume, untested ).

What could end up happening is a build script could be set up which spits out multiple versions of scatter-js with blockchain suffixes ( -eos, -eth ) however that might be limited in the future as more blockchains are added and combinations would want to be formed.

I'll definitely have to run some tests on constructor methods and see if requiring specific signature providers cuts down esm/cjs sizes, but likely it'll have to be handled manually for the pre-bundled browser versions.

I'm not that familiar with lerna itself but am with that structure, this looks like a great solution for importation of nodejs packages. I'll have to dig into this when time permits. Feel free to PR an example <3

Would this support also browser only imports ( CDN based ) in the same fashion?

Implemented and merged into master.
Thanks oodles for the help on this, made life super-easy.
