Allow List of Lists and SequenceExample in dict_to_example

[AlexanderLavelle]

System information

• TFX Version (you are using): 1.14.0
• Environment in which you plan to use the feature (e.g., Local
  (Linux/MacOS/Windows), Interactive Notebook, Google Cloud, etc..): Linux (anywhere)
• Are you willing to contribute it (Yes/No): Yes

Describe the feature and the current behavior/state.
The current behavior will not allow a list of lists because list is not an acceptable type (int, str, float). The feature allows a list of lists to be encoder (per sequence modeling etc)

Will this change the current API? How?
The current API will not be affected, although user experience on the read varies -- this function as a standalone with the writer is fine, but a user who does not implement 5689 will not see the Sequences encoded as a result of this modification

Who will benefit with this feature?
Users who want to do sequence modeling whose native data is list of lists or tf.RaggedTensors

Do you have a workaround or are completely blocked by this? :
This is the workaround

Name of your Organization (Optional)
