Add ADL5303 logarithmic amplifier

Usage example: Please keep in mind that there are a lot of different ways to configure this. This is just one of them.

I tried simplifying the datasheet graphics so it still makes some sense in context. This is loosely based on my LOG114 symbol.

Note that VSUM is intended to be used as a guard ring. VPDB ist the photodiode bias.
