Implement depth option for detaild report

[garthenweb]

↪️ Pull Request

Allows define a depth for the detailedReport option. Implements #1857.

💻 Examples

Show all assets used within bundles:

new Bundler('./path/to/file.ts', { detailedReport: 'all' });

Show the largest 50 assets per bundle:

parcel build ./path/to/file.ts --detailed-report=50

🚨 Test instructions

With this changes, when the --detailed-report argument is used via cli without an option, it must be used after the path to the resource, because otherwise it would use the file name as its value.

Right: parcel build ./path/to/file.ts --detailed-report
Wrong: parcel build --detailed-report ./path/to/file.ts

Not sure if this is considered a breaking change for parcel, I did not found a good way to solve this using commander which is used for parsing the command on the shell.
