I removed unused dependencies including eosjs-ecc by scoping out depcheck and running npm test-all after every npm uninstall <unused_dependency>

Dependencies removed:

• eslist
• pako
• @cypress/skip-test
• @types/node
• @types/node-fetch
• @types/pako
• clean-webpack-plugin
• crypto-browserify
• rimraf
• ts-loader
• typedoc
• typedoc-markdown-theme
• webpack-cli

I also modified the package.json file's scripts to run npm instead of yarn. This is a part of https://github.com/eosnetworkfoundation/mandel-eosjs/issues/12. Further clean up will be done in a separate ticket.

Testing

I used modified version of npm test-all to test against the removed dependencies. NOTE: Cypress test was failing. Investigation could be further discussed with team.

I see the yarn.lock still there and modified, but your comment said you deleted it, maybe it got added back on or something?
