      This patch adds a go-multiaddr CLI to aid in testing this
implementation of multiaddr. It takes a multiaddr in string or
packed form as input, and prints detailed information about the
multiaddr. This tool can be useful beyond testing, of course.

Another addition is a Makefile target for running the new
multiaddr conformance test suite. This test suite lives at
https://github.com/multiformats/multiaddr and is fetched to be
run against our new go-multiaddr CLI. This target is to be run in CI

Neither the test suite nor the CLI are complete yet.

Currently the output looks like this:

```
> go run ./multiaddr /ip4/192.0.2.42/tcp/443 | jq .
{
  "string": "/ip4/192.0.2.42/tcp/443",
  "stringSize": "23",
  "packed": "0x04c000022a0601bb",
  "packedSize": "8",
  "components": [
    {
      "string": "/ip4/192.0.2.42",
      "stringSize": "15",
      "packed": "0x04c000022a",
      "packedSize": "5",
      "value": "192.0.2.42",
      "rawValue": "0xc000022a",
      "valueSize": "4",
      "protocol": "ip4",
      "codec": "4",
      "uvarint": "0x04",
      "lengthPrefix": ""
    },
    {
      "string": "/tcp/443",
      "stringSize": "8",
      "packed": "0x0601bb",
      "packedSize": "3",
      "value": "443",
      "rawValue": "0x01bb",
      "valueSize": "2",
      "protocol": "tcp",
      "codec": "6",
      "uvarint": "0x06",
      "lengthPrefix": ""
    }
  ]
}
```

And the Makefile target:

```
> make conformance
go get -d -v .
go build -o tmp/multiaddr/test/go-multiaddr ./multiaddr
cd tmp/multiaddr/test && MULTIADDR_BIN="./go-multiaddr" go test -v
=== RUN   TestGodog
MULTIADDR_BIN="./go-multiaddr"
