feat: convert to typescript

[achingbrain]

• Converts to typescript
• Only named exports
• No more CJS, only ESM
• Runs tests on all supported environments
• Adds auto-publish
• Adds dependabot
• Drops dependency on simple-peer as it has deps on Buffer, node streams, etc

BREAKING CHANGE: switch to named exports, ESM only

[achingbrain]

The tests pass on node but then wrtc does a SIGSEGV when shutting down.
