Latest version is broken in browserify?

Seeing this in CI:

example-browser-browserify: > example-browser-browserify@1.1.1 test /home/travis/build/ipfs/js-ipfs/examples/browser-browserify
example-browser-browserify: > test-ipfs-example
example-browser-browserify: > example-browser-browserify@1.1.1 bundle /home/travis/build/ipfs/js-ipfs/examples/browser-browserify
example-browser-browserify: > browserify src/index.js > public/bundle.js
example-browser-browserify: /home/travis/build/ipfs/js-ipfs/node_modules/web-encoding/src/lib.js:7
example-browser-browserify: export { Encoder as TextEncoder, Decoder as TextDecoder }
example-browser-browserify: ^
example-browser-browserify: ParseError: 'import' and 'export' may appear only with 'sourceType: module'

I think this is because browser points to esm and it needs to point to cjs, then use exports to override to esm for environments that support esm.

The 'node' key can be used in package.exports to supply something specifically to node versions that support package.exports - maybe that could be where the require('utils') lives?
