Decode a IBLT sketch.

This function wraps IbltDecoder to decode iblt and returns frequencies of decoded strings.

iblt Tensor representing the IBLT computed by the IbltEncoder.
capacity Number of distinct strings that we expect to be inserted.
string_max_bytes Maximum length of a string in bytes that can be inserted.
encoding The character encoding of the string data to decode. For non-character binary data or strings with unknown encoding, specify CharacterEncoding.UNKNOWN.
seed Integer seed for hash functions. Defaults to 0.
repetitions Number of repetitions in IBLT data structure (must be >= 3). Defaults to 3.
hash_family A str specifying the hash family to use to construct IBLT. Options include coupled or random, default is chosen based on capacity.
hash_family_params An optional dict of parameters that the hash family hasher expects. Defaults are chosen based on capacity.
field_size The field size for all values in IBLT. Defaults to 2**31 - 1.

(out_strings, out_counts, num_not_decoded) where out_strings is a tf.Tensor containing all the decoded strings, out_counts is a tf.Tensor containing the counts of each string and num_not_decoded is a tf.Tensor with the number of items not decoded in the IBLT.
