Write get_config for below code:
class CustomLayer(tf.keras.layers.Layer):

def __init__(self, pool_size=3, strides=1, padding='valid', **kwargs):
super(CustomLayer, self).__init__(**kwargs)
self.pool_size = pool_size
self.strides = (1, strides, strides, 1)
self.padding = 'VALID' if padding == 'valid' else 'SAME'
****some methods and definitions
