✨ add option to override build_extension

[techouse]

Gives the user the ability to override the generated file extension from .chopper.dart to whatever they want, i.e. .chopper.g.dart.

To use this feature you have to create a build.yaml file in your project's root directory and add the following lines

targets:
  $default:
    builders:
      chopper_generator:
        options:
          # This assumes you want the files to end with `.chopper.g.dart`
          # instead of the default `.chopper.dart`.
          build_extensions: {".dart": [".chopper.g.dart"]}

Note that using this feature means that you will also have to change the part declarations in your dart files, i.e.

from

part 'my_service.chopper.dart';

to

part 'my_service.chopper.g.dart';
