  Max pooling operation for 1D temporal data.

Downsamples the input representation by taking the maximum value over a
spatial window of size `pool_size`. The window is shifted by `strides`.  The
resulting output, when using the `"valid"` padding option, has a shape of:
`output_shape = (input_shape - pool_size + 1) / strides)`

The resulting output shape when using the `"same"` padding option is:
`output_shape = input_shape / strides`

For example, for `strides=1` and `padding="valid"`:

>>> x = tf.constant([1., 2., 3., 4., 5.])
>>> x = tf.reshape(x, [1, 5, 1])
>>> max_pool_1d = tf.keras.layers.MaxPooling1D(pool_size=2,
...    strides=1, padding='valid')
>>> max_pool_1d(x)
<tf.Tensor: shape=(1, 4, 1), dtype=float32, numpy=
array([[[2.],
        [3.],
        [4.],
        [5.]]], dtype=float32)>

For example, for `strides=2` and `padding="valid"`:

>>> x = tf.constant([1., 2., 3., 4., 5.])
>>> x = tf.reshape(x, [1, 5, 1])
>>> max_pool_1d = tf.keras.layers.MaxPooling1D(pool_size=2,
...    strides=2, padding='valid')
>>> max_pool_1d(x)
<tf.Tensor: shape=(1, 2, 1), dtype=float32, numpy=
array([[[2.],
        [4.]]], dtype=float32)>

For example, for `strides=1` and `padding="same"`:

>>> x = tf.constant([1., 2., 3., 4., 5.])
>>> x = tf.reshape(x, [1, 5, 1])
>>> max_pool_1d = tf.keras.layers.MaxPooling1D(pool_size=2,
...    strides=1, padding='same')
>>> max_pool_1d(x)
<tf.Tensor: shape=(1, 5, 1), dtype=float32, numpy=
array([[[2.],
        [3.],
        [4.],
        [5.],
        [5.]]], dtype=float32)>

Args:
  pool_size: Integer, size of the max pooling window.
  strides: Integer, or None. Specifies how much the pooling window moves
    for each pooling step.
    If None, it will default to `pool_size`.
  padding: One of `"valid"` or `"same"` (case-insensitive).
    `"valid"` means no padding. `"same"` results in padding evenly to
    the left/right or up/down of the input such that output has the same
    height/width dimension as the input.
  data_format: A string,
    one of `channels_last` (default) or `channels_first`.
    The ordering of the dimensions in the inputs.
    `channels_last` corresponds to inputs with shape
    `(batch, steps, features)` while `channels_first`
    corresponds to inputs with shape
    `(batch, features, steps)`.

Input shape:
  - If `data_format='channels_last'`:
    3D tensor with shape `(batch_size, steps, features)`.
  - If `data_format='channels_first'`:
    3D tensor with shape `(batch_size, features, steps)`.

Output shape:
  - If `data_format='channels_last'`:
    3D tensor with shape `(batch_size, downsampled_steps, features)`.
  - If `data_format='channels_first'`:
    3D tensor with shape `(batch_size, features, downsampled_steps)`.
