Switch wallet tsconfig to use esnext module

[snario]

In order to use dynamic imports, we need to use the import(...) syntax. TypeScript doesn't know how to handle this with commonjs, so we need to use esnext.

In order to use WebAssembly in the browser we need to use dynamic imports.

In order to use pure-evm, we need to use WebAssembly, which means we need dynamic imports.

The integration tests use ts-node, which uses Node.js, which can't handle ES modules. See TypeStrong/ts-node#436.

So, I need to use commonjs for the puppeteer/funding.ts test script. Note that this is just for the test script, which launches a browser, which runs the webpack output, which was built from the TypeScript source compiled using esnext.

I noticed webpack's stats.warningsFilter doesn't seem to work. Also it doesn't work in the browser at all: webpack-contrib/webpack-hot-client#94. That might be an issue.

Also jsonrpc-lite started raising this warning: teambition/jsonrpc-lite#15

Ugh I think this might be blocked on #593 because the hub uses ts-node and imports the wallet for certain things.
