[ZM_U] Allows Samus to destroy multiple bomb chain blocks of the same type at once.

Especially useful if you use the tweak that makes chain blocks destroyable with speed booster/screw attack:

0x8345ACC: 12 10 -> ?? 10
0x8345ACE: 12 10 -> ?? 10
0x8345AD0: 12 10 -> ?? 10
0x8345AD2: 12 10 -> ?? 10
0x8345AD4: 12 10 -> ?? 10
0x8345AD6: 12 10 -> ?? 10
0x8345AD8: 12 10 -> ?? 10
0x8345ADA: 12 10 -> ?? 10

92: Can also be destroyed with screw attack
B2: Can also be destroyed with screw attack and speed booster

Also prevents power bombs from missing some chain blocks on screen.
