We define a new operation as follows: $a$※$b=2ab-\frac{b}{2}$, where the symbol "※" represents this new operation. For example, $3$※$\left(-2\right)=2\times 3\times \left(-2\right)-\frac{-2}{2}=-12+1=-11$. Calculate the following expressions based on this new definition:<br/>
$(1)\left(-5\right)$※$4$;<br/>
$(2)\left(-3\right)$※$\left(-6\right)$.
