itu-rad/tensorsocket: TensorSocket 0.0.5

TensorSocket 0.0.5 (also on PyPI: https://pypi.org/project/tensorsocket/0.0.5/). Version used by the SIGMOD 2026 reproducibility package (https://github.com/itu-rad/tensorsocket-reproduction).

Fixes:

• Consumers now end an epoch correctly.
• The producer no longer stalls when the rubber-band buffer is smaller than one producer batch.
• TensorConsumer.__len__ reports the right number of batches with flexible batch sizes.
• The producer's memory no longer grows without bound with small loader batches (fixed glibc mmap threshold).
