feat: type check & generate defs from jsdoc (#3281)

1. Add missing type info (via jsdoc) and fix existing one so that `tsc --noEmit` can succeed without an error.
2. Fix all the issues that `tsc` pointed out once it got enabled.
3. Add a npm script that generates typedefs & typedef maps in `dist` directory & corresponding settings in `package.json` so that when package installed from npm no config will be required to get all the typings.

 * `headers` - An object or [Headers](https://developer.mozilla.org/en-US/docs/Web/API/Headers) instance that can be used to set custom HTTP headers. Note that this option can also be [configured globally](#custom-headers) via the constructor options.
 * `searchParams` - An object or [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) instance that can be used to add additional query parameters to the query string sent with each request.

-* `ipld.loadFormat` an async function that takes the name of an [IPLD format](https://github.com/ipld/interface-ipld-format) as a string and should return the implementation of that codec
