v1.0.2 Packaging and installation * Installed Parquet support by default by shipping the package with the required dependency out of the box, refreshed the installation guidance, refined optional-dependency messaging, and added package-metadata regression coverage. Resolved issue `#142 <https://github.com/it-is-me-mario/MARIO/issues/142>`_. SUT scenarios and native matrix workflows Extended SUT scenario updates so unified Z, Y and E inputs are accepted directly and normalized through the shared ordering logic, with dedicated regression tests for the new update paths. Resolved issue #144 <https://github.com/it-is-me-mario/MARIO/issues/144>_. Switched SUT export and parser roundtrips to native SUT blocks instead of legacy unified IOT-style matrices, while preserving backward-compatible parsing of historical TXT, Parquet and Excel layouts. Resolved issue #146 <https://github.com/it-is-me-mario/MARIO/issues/146>_. Parser and export roundtrip fixes * Fixed ``coefficients``-mode parsing of native SUT and special-layout IOT bundles from TXT and Parquet, which raised ``KeyError: 'Z'`` because the index builders only looked up the upper-case flow matrix name. * Fixed the explicit SUT Excel export so productive columns are written in the same commodity-first order as the rows, allowing workbooks with overlapping ``Activity``/``Commodity`` item labels to round-trip correctly. * Fixed flat TXT/CSV parsing of standard IOT bundles, which raised ``ValueError: not enough values to unpack`` due to an inconsistent parser return signature. * Added a full export/parse roundtrip test matrix covering the ``standard`` and ``special`` layouts across Excel, TXT and Parquet in both ``flows`` and ``coefficients`` modes.
