Add declarationMap:true to tsconfig for correct ctrl-click go-to-source

[wingedrhino]

Currently, ctrl+click on a tinyhttp export from VS Code goes to the .d.ts file instead of going to the function source code. Adding "declarationMap": true to tsconfig.json would generate .js.map files. For example, take a look here https://github.com/wingedrhino/node-pipespawn/tree/master/dist

I'd love to add this to tinyhttp, but every other package that's been moved to its own dedicated repository would also need to be updated for this to be actually useful.

If you're happy to accept merge requests, I can start submitting them one at a time!

I'm not sure tbh if it's worth increasing the package size for that but it's not that important for backend so let's go

This shouldn't increase RAM use! And depending on how the end-user configures their tsconfig.json (or webpack), it can also be stripped out of the final build.

Alight, sending a few pull requests your way this weekend!

I'll take this up.

Was looking at ts docs and I reckon we should turn on sourceMap and composite. sourceMap helps map the ts files and composite decreases type checking time since it references previous built files.
