David Peterson c3d1f72556 Add null string sentinel handling in load_sas.py for improved missing value detection ... Introduced a frozenset of string literals that represent SQL NULL values, enhancing the inference and nullability detection processes. Implemented helper functions to identify null strings and unify missing value checks for CHAR/TEXT columns. Updated the _null_sentinel_mask function to replace these sentinel values with None, ensuring consistent handling across various data types during data loading. This change improves robustness in managing missing data scenarios.		2026-04-22 19:20:07 -05:00
