Added yet another impedance calculator

[T3sl4co1l]

In my ever-growing series of inductor measurement tools, I've added one with a series matching capacitor topology, so you can get more power into the tank from a function generator:

Kinda fun to actually palpably heat up a large-value inductor just under signal generator power.

Let me know if you find any discrepancies!
