Migrate from Lerna to npm workspaces

[dselman]

lerna publish is now creating errors with newer version of npm. This PR removes Lerna from this mono repo, replacing it with the built in npm --workspaces commands.

Lerna error:

ERR! bootstrap The "bootstrap" command was removed by default in v7, and is no longer maintained.

Changes

• Remove lerna
• Update scripts to use npm workspaces
• Remove some dead package.json entries
• Fix web pack config
• Removed the dingus UI. This is(somewhat) superseded by https://playground.accordproject.org.
