This pull request updates the handling of the bad_time_flag_occurrences variable in the GLOWS L2 data processing pipeline to use an unsigned 16-bit integer type, increases its valid range, and adds a test to verify the new data type. These changes ensure the variable can represent a larger range of values and are consistent across the configuration, code, and tests.

Data type and range updates:

• Changed the bad_time_flag_occurrences array in glows_l2_data.py to use np.uint16 for a wider valid range and better memory efficiency.
• Updated the configuration in imap_glows_l2_variable_attrs.yaml to set FILLVAL to 65535, and changed VALIDMIN to 0 and VALIDMAX to 65535, aligning with the new data type.

Testing improvements:

• Added a test in test_glows_l2.py to assert that bad_time_flag_occurrences uses the np.uint16 data type, ensuring correctness of the change.
