Pose fps treated as integer instead of float

[bricksdont]

In certain places, e.g. :

datasets/sign_language_datasets/utils/features/pose_feature.py

Line 127 in d71f97f

"fps": feature.TensorInfo(shape=(), dtype=tf.int32),

in the code fps is treated as int instead of float, or cast to int:

datasets/sign_language_datasets/utils/features/pose_feature.py

Line 147 in d71f97f

encoded = {"data": data, "conf": confidence, "fps": int(body.fps)}

losing some precision.
