Updated the default values of 15 runtime parameters, as agreed upon in a MOM6 consortium wide conversations on July 29, 2024 and December 16, 2024. The most prominent of these is that the default equation of state is now EQN_OF_STATE = "WRIGHT_FULL", in place of the buggy previous default of "WRIGHT".

The 8 answer date parameters REGRIDDING_ANSWER_DATE, TIDES_ANSWER_DATE, WAVE_INTERFACE_ANSWER_DATE, MEKE_GM_SRC_ANSWER_DATE, NDIFF_ANSWER_DATE, KPP%ANSWER_DATE, HOR_DIFF_ANSWER_DATE and LOTW_BBL_ANSWER_DATE all now take their default values from DEFAULT_ANSWER_DATE.

The bug-retention parameters MEKE_GM_SRC_ALT_SLOPE_BUG, HOR_DIFF_LIMIT_BUG, BACKSCATTER_UNDERBOUND, DETERMINE_TEMP_CONVERGENCE_BUG, LA_MISALIGNMENT_BUG and IDL_HURR_SCM_EDGE_TAPER_BUG are now false by default.

Bitwise identical answers are recovered if all 15 of these parameters are set explicitly, but answers can change if any of these parameters take default values. All of these default changes are the consensus decision of consortium-wise MOM6 dev calls.

  Updated the default values of 15 runtime parameters, as agreed upon in a MOM6
consortium wide conversations on July 29, 2024 and December 16, 2024.  The most
prominent of these is that the default equation of state is now EQN_OF_STATE =
"WRIGHT_FULL", in place of the buggy previous default of "WRIGHT".

  The 8 answer date parameters REGRIDDING_ANSWER_DATE, TIDES_ANSWER_DATE,
WAVE_INTERFACE_ANSWER_DATE, MEKE_GM_SRC_ANSWER_DATE, NDIFF_ANSWER_DATE,
KPP%ANSWER_DATE, HOR_DIFF_ANSWER_DATE and LOTW_BBL_ANSWER_DATE all now take
their default values from DEFAULT_ANSWER_DATE.

  The bug-retention parameters MEKE_GM_SRC_ALT_SLOPE_BUG, HOR_DIFF_LIMIT_BUG,
BACKSCATTER_UNDERBOUND, DETERMINE_TEMP_CONVERGENCE_BUG, LA_MISALIGNMENT_BUG and
IDL_HURR_SCM_EDGE_TAPER_BUG are now false by default.

  The MOM_input files for the test cases in the `.testing/tc[01234]` directories
were updated to explicitly set all of these parameters to their previous default
values.

  Bitwise identical answers are recovered if all 15 of these parameters are set
explicitly, but answers can change if any of these parameters take default
values.  All of these default changes are the consensus decision of
consortium-wise MOM6 dev calls.
