PadIfNeeded doesn't serialize position parameter

[margilt]

🐛 Bug

The PadIfNeeded transform doesn't serialize the position parameter.

To Reproduce

Steps to reproduce the behavior:

import albumentations as A
transform = A.PadIfNeeded(min_height=512, min_width=512, p=1, border_mode=0, value=[124, 116, 104], position="top_left")
transform.to_dict()

Output:

{'__version__': '1.4.1', 'transform': {'__class_fullname__': 'PadIfNeeded', 'always_apply': False, 'p': 1, 'min_height': 512, 'min_width': 512, 'pad_height_divisor': None, 'pad_width_divisor': None, 'border_mode': 0, 'value': [124, 116, 104], 'mask_value': None}}

Expected behavior

The position parameter should be included in the dict.

Environment

• Albumentations version: 1.4.1
• Python version: 3.8
• OS: Linux
• How you installed albumentations (conda, pip, source): pip
