Convert a string or byte-like object to an opcode and a bytes-like object.

    This function is designed for data frames.

    If ``data`` is a :class:`str`, return ``OP_TEXT`` and a :class:`bytes`
    object encoding ``data`` in UTF-8.

    If ``data`` is a bytes-like object, return ``OP_BINARY`` and a bytes-like
    object.

    Raise :exc:`TypeError` for other inputs.
