[Bug]: API Examples and Documentation are broken due to pull #2847

[DrCyanide]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits of both this extension and the webui

What happened?

Pull request #2847 broke backwards compatibility with "control_mode": 0,, which is used in the examples.

It also broke the documentation at https://github.com/Mikubill/sd-webui-controlnet/wiki/API#controlnetunitrequest-json-object for what values are expected.

Steps to reproduce the problem

Try to run the example api code that's provided in this repo.

What should have happened?

The code should work, not return an error.

Console logs

Running api_txt2img.py as is returns this:

Traceback (most recent call last):
  File "D:\Documents\AI\ImgGen\a1111_1.9.3\stable-diffusion-webui\extensions\sd-webui-controlnet\example\txt2img_example\api_txt2img.py", line 74, in <module>
    result = output['images'][0]
KeyError: 'images'

Modifying it to print(output) instead returns this:

{'error': 'ValidationError', 'detail': '', 'body': '', 'errors': "2 validation errors for ControlNetUnit\nresize_mode\n   (type=assertion_error)\ncontrol_mode\n  value is not a valid enumeration member; permitted: 'Balanced', 'My prompt is more important', 'ControlNet is more important' (type=type_error.enum; enum_values=[<ControlMode.BALANCED: 'Balanced'>, <ControlMode.PROMPT: 'My prompt is more important'>, <ControlMode.CONTROL: 'ControlNet is more important'>])"}
