feat!: convert codebase to typescript (#251)

Fixes #249

- update aegir to get latest linter rules
- minimal changes to vendored code
  - eslint-disable files, add inferred types as jsdocs, move vendor directory under src
- convert all .js files to .ts
- apply all jsdoc type annotations as typescript type annotations
- fix all resulting linter and type issues
- Special attention given to keep any helpful jsdocs

BREAKING CHANGE: this module is now TypeScript - the API has not changed but releasing as a major for saftey

-## Interfaces
+# About
 
 This library defines common interfaces and low level building blocks for various interrelated multiformat technologies (multicodec, multihash, multibase, and CID). They can be used to implement custom base encoders / decoders / codecs, codec encoders /decoders and multihash hashers that comply to the interface that layers above assume.
 
 This library provides implementations for most basics and many others can be found in linked repositories.

+## Multibase Encoders / Decoders / Codecs
 
 CIDs can be serialized to string representation using multibase encoders that implement [`MultibaseEncoder`](https://github.com/multiformats/js-multiformats/blob/master/src/bases/interface.ts) interface. This library provides quite a few implementations that can be imported:
 
-```js
+```TypeScript
 import { base64 } from "multiformats/bases/base64"
 cid.toString(base64.encoder)
 //> 'mAYAEEiCTojlxqRTl6svwqNJRVM2jCcPBxy+7mRTUfGDzy2gViA'
 ```
 
 Parsing CID string serialized CIDs requires multibase decoder that implements [`MultibaseDecoder`](https://github.com/multiformats/js-multiformats/blob/master/src/bases/interface.ts) interface. This library provides a decoder for every encoder it provides:
 
-```js
+```TypeScript
 CID.parse('mAYAEEiCTojlxqRTl6svwqNJRVM2jCcPBxy+7mRTUfGDzy2gViA', base64.decoder)

+## Multicodec Encoders / Decoders / Codecs
 
 This library defines [`BlockEncoder`, `BlockDecoder` and `BlockCodec` interfaces](https://github.com/multiformats/js-multiformats/blob/master/src/codecs/interface.ts).
 Codec implementations should conform to the `BlockCodec` interface which implements both `BlockEncoder` and `BlockDecoder`.
 Here is an example implementation of JSON `BlockCodec`.
 
-```js
-/**
- * @template T
- * @type {BlockCodec<0x0200, T>}

-### Traversal
+## Traversal
 
 This library contains higher-order functions for traversing graphs of data easily.
 
 `walk()` walks through the links in each block of a DAG calling a user-supplied loader function for each one, in depth-first order with no duplicate block visits. The loader should return a `Block` object and can be used to inspect and collect block ordering for a full DAG walk. The loader should `throw` on error, and return `null` if a block should be skipped by `walk()`.

+```TypeScript
