Created bxpb-runtime package.

Refs #1.

Generated the package with:

```
$ npm run lerna create bxpb-runtime

> root@ lerna /home/dparker/Source/bxpb
> lerna "create" "bxpb-runtime"

lerna notice cli v3.20.2

Additional edits were deleting the generated JavaScript code and dropping the `main`, `files`, and `directories` keys in the `package.json` file. I'll re-add those as they become relevant. I also filled in the README with expected usage details.

+# `bxpb-runtime`
+
+Implements the runtime for clients and services using `bxpb`.
+
+## Usage
+
+Services should use `serve()` to listen to a message passing API and run a service on it.
+
+```typescript
+import { serve } from 'bxpb-runtime/service';
+import { GreeterService } from 'protos/greeter_bx';
+import { HelloRequest, HelloResponse } from 'protos/greeter_pb';
+
+serve(chrome.runtime.onMessage, MyProtoService, {
+    // Implement methods of the service.
+    async greet(req: HelloRequest): Promise<HelloResponse> {
+        const res = new HelloResponse();
+        res.setMessage(`Hello, ${req.getName()}!`);
+        return res;
+    },
+});
+```
+
+Clients should extend `ProtoClient` for a given service they want to call.
+
+```typescript
+import { ProtoClient } from 'bxpb-runtime/client';
+import { GreeterService } from 'protos/greeter_bx';
+import { HelloRequest, HelloResponse } from 'protos/greeter_pb';
+
+class GreeterClient extends ProtoClient {
+    async greet(req: HelloRequest): Promise<HelloResponse> {
+        return await this.makeRpc(GreeterService, GreeterService.methods.greet, req);
+    }
+}
+
+(async () => {
+    const req = new HelloRequest();
+    req.setName('Dave');
+
+    const client = new GreeterClient(chrome.runtime.sendMessage);
+    const res = await client.greet(req);
+
+    console.log(res.getMessage()); // 'Hello, Dave!'
+})();
+```
+
+Client classes are typically generated by `bxpb-protoc-plugin` and not hand-written.
