Robotron: 2084: Routine at C702

Used by the routines at Main_Game_Loop, Animate_Wave_Start_Sequence, Dispatch_Narrow_Entity_Approach and Stage_Next_Wave.

Chained trampoline: pushes resume address DispatchWordFromHL, loads a 16-bit routine pointer from HL, advances HL by 02 then jumps to that pointer via the stack. When the handler RETs, execution continues at DispatchWordFromHL for the next table entry, so handlers should leave HL valid for the following word unless the chain ends. Used from CC5F, CEBF, CF45, D27C with tables such as Entity_List_Base.

DispatchWordFromHL	C702	LD DE,$C702	DE=DispatchWordFromHL (resume address after each nested RET).
	C705	PUSH DE	Save the resume address on the stack.
	C706	LD E,(HL)	E=*HL (handler pointer, low byte).
	C707	INC HL	Advance HL.
	C708	LD D,(HL)	D=*HL (handler pointer, high byte).
	C709	INC HL	Advance HL past the pointer.
	C70A	PUSH DE	Stack the handler address.
	C70B	RET	RET to the handler (next RET pops back to DispatchWordFromHL).
