`caste_body_info::unk_v40_2` update

[ab9rf]

in caste_body_info, elements 5 through 9 of unk_v40_2 are gait values (WALK, FLY, SWIM, CRAWL, and CLIMB, respectively)

this based on code reverse engineered from 50.09-steam @ 0x1410cb097-0x1410cb0e4 (pcVar12 is a caste_body_info *, param_1 is a unitst *)

          pcVar12 = (param_1->body).body_plan;
          (param_1->enemy).gait_index.WALK = pcVar12->unk_v40_2[5];
          (param_1->enemy).gait_index.FLY = pcVar12->unk_v40_2[6];
          (param_1->enemy).gait_index.SWIM = pcVar12->unk_v40_2[7];
          (param_1->enemy).gait_index.CRAWL = pcVar12->unk_v40_2[8];
          (param_1->enemy).gait_index.CLIMB = pcVar12->unk_v40_2[9];

no intel on what elements 0-4 or 10 are, presumably will need to split unk_v40_2
