    operations such as categorical feature encoding, text vectorization, data
    normalization, and data discretization (binning). The newly added layers
    provide a replacement for the legacy feature column API, and support
    composite tensor inputs.
*   Added **categorical data** processing layers:
    *   `IntegerLookup` & `StringLookup`: build an index of categorical feature
        values
