Subject: [PATCH] feat(bob): add exclude option to config (#450)

### Summary

This adds the possibility to pass custom ignore patterns while working
with builder bob.

### Test plan

1. Create a new library using `create-react-native-library`. You can
select `Native module`, and `Kotlin & Swift` options.
2. Go to `package.json`, and find the `react-native-builder-bob` section
3. Replace `commonjs` target as following:
```json
{
    "exclude": "**/ignore_me/**"
    "targets": [
      "commonjs",
      "module",
      [
        "typescript",
        {
          "project": "tsconfig.build.json"
        }
      ]
    ]
}
```
4. Create a new folder named `src/ignore_me` and put `.ts` files inside
it
5. Build the library and make sure the files inside the `ignore_me`
aren't included in the `commonjs` and `module` targets.

+Glob pattern to be used while filtering the unnecessary files. Defaults to `'**/{__tests__,__fixtures__,__mocks__}/**'` if you don't specify it.
