Generate .d.ts files

[jespertheend]

It seems like deno doesn't have great support for parsing JSDoc types. This has several effects:

• API Documentation is not great, for example https://deno.land/x/renda@v0.1.0/src/mod.js?s=Vec3 does show all class methods. But the types of arguments are missing.
• jsr.io treats the package as having 'slow types' for the same reason: https://jsr.io/@renda/renda/score
• tsickle could possibly be used to generate a bundled version of renda that is compatible with Google Closure Compiler's 'advanced' mode.

There's some documentation on how to do this here: https://www.typescriptlang.org/docs/handbook/declaration-files/dts-from-js.html

I tried running this in the jsrPackage directory:

npx -p typescript tsc mod.js --declaration --allowJs --emitDeclarationOnly --outDir .

I had reasonable success with this. Although it seems like it is incredibly slow right now. It's generating lots of large types for binarySerialization.js. We might have to convert binarySerializationTypes.ts to JSDoc as well (#791 related)
