Module integer 

Integer encoding using Delta + ZigZag + variable-length bit-packing.

Encoders

• IntegerEncoder: Delta + ZigZag + fixed-width bit-packing. Optimal for monotonic or slowly-changing sequences where all deltas have a similar magnitude.

• VarintEncoder: Delta + ZigZag + LEB128 varint per delta. Optimal for sparse or highly variable data where most deltas are small but occasional outliers would inflate the fixed bit width.

Both encoders compute deltas between consecutive values and ZigZag-encode them, but differ in how the unsigned deltas are serialised.
