feat: convert to typescript (#1172)
Converts this module to typescript.

- Ecosystem modules renamed from (e.g.) `libp2p-tcp` to `@libp2p/tcp`
- Ecosystem module now have named exports
- Configuration has been updated, now pass instances of modules instead of classes:
- Some configuration keys have been renamed to make them more descriptive.  `transport` -> `transports`, `connEncryption` -> `connectionEncryption`.  In general where we pass multiple things, the key is now plural, e.g. `streamMuxer` -> `streamMuxers`, `contentRouting` -> `contentRouters`, etc.  Where we are configuring a singleton the config key is singular, e.g. `connProtector` -> `connectionProtector` etc.
- Properties of the `modules` config key have been moved to the root
- Properties of the `config` config key have been moved to the root
```js
// before
import Libp2p from 'libp2p'
import TCP from 'libp2p-tcp'

await Libp2p.create({
  modules: {
    transport: [
      TCP
    ],
  }
  config: {
    transport: {
      [TCP.tag]: {
        foo: 'bar'
      }
    },
    relay: {
      enabled: true,
      hop: {
        enabled: true,
        active: true
      }
    }
  }
})
```
```js
// after
import { createLibp2p } from 'libp2p'
import { TCP } from '@libp2p/tcp'

await createLibp2p({
  transports: [
    new TCP({ foo: 'bar' })
  ],
  relay: {
    enabled: true,
    hop: {
      enabled: true,
      active: true
    }
  }
})
```
- Use of `enabled` flag has been reduced - previously you could pass a module but disable it with config.  Now if you don't want a feature, just don't pass an implementation.   Eg:
```js
// before
await Libp2p.create({
  modules: {
    transport: [
      TCP
    ],
    pubsub: Gossipsub
  },
  config: {
    pubsub: {
      enabled: false
    }
  }
})
```
```js
// after
await createLibp2p({
  transports: [
    new TCP()
  ]
})
```
- `.multiaddrs` renamed to `.getMultiaddrs()` because it's not a property accessor, work is done by that method to calculate announce addresses, observed addresses, etc
- `/p2p/${peerId}` is now appended to all addresses returned by `.getMultiaddrs()` so they can be used opaquely (every consumer has to append the peer ID to the address to actually use it otherwise).  If you need low-level unadulterated addresses, call methods on the address manager.

BREAKING CHANGE: types are no longer hand crafted, this module is now ESM only

feat: async peerstore backed by datastores (#1058)
We have a peerstore that keeps all data for all observed peers in memory with no eviction.

This is fine when you don't discover many peers but when using the DHT you encounter a significant number of peers so our peer storage grows and grows over time.

We have a persistent peer store, but it just periodically writes peers into the datastore to be read at startup, still keeping them in memory.

It also means a restart doesn't give you any temporary reprieve from the memory leak as the previously observed peer data is read into memory at startup.

This change refactors the peerstore to use a datastore by default, reading and writing peer info as it arrives.  It can be configured with a MemoryDatastore if desired.

It was necessary to change the peerstore and *book interfaces to be asynchronous since the datastore api is asynchronous.

BREAKING CHANGE: `libp2p.handle`, `libp2p.registrar.register` and the peerstore methods have become async

chore: run node tests in ci (#1057)
Looks like this project stopped running the `test:node` npm script when it was migrated to gh actions.

Re-enable it and fix all the related test failures.

fix: store multiaddrs during content and peer routing queries (#865)
* fix: store provider multiaddrs during find providers

Changes the behaviour of `libp2p.contentRouting.findProviders` to store
the multiaddrs reported by the routers before yielding results to
the caller, so when they try to dial the provider, the multiaddrs are
already in the peer store's address book.

Also dedupes providers reported by routers but keeps all of the addresses
reported, even for duplicates.

Also, also fixes a performance bug where the previous implementation would
wait for any router to completely finish finding providers before sending
any results to the caller.  It'll now yield results as they come in which
makes it much, much faster.
