biometeorology_mod.f90:
(C) Allocation of the input _av grids was moved to the "sum" section of bio_3d_data_averaging to make sure averaging is only done once!
(B) Moved call of bio_calculate_thermal_index_maps from biometeorology module to time_integration (ll 1712) to make sure averaged input is updated before calculating.

time_integration.f90:
(B) Moved call of bio_calculate_thermal_index_maps from biometeorology module to time_integration (ll 1712) to make sure averaged input is updated before calculating.
