Fluidlogged API support

[jbredwards]

Add an optional Fluidlogged API dependency, instead of re-implementing fluidlogging logic from scratch.

Pros:

• Common logic for fluidlogging (automatic compatibility with other mods that use Fluidlogged API).
• Much more robust (Fluidlogged API has been in development for years).

Cons:

• Players have to install another mod if they want to fluidlog a copper grate, if they don't already have Fluidlogged API.

This is a prototype system for functionality that will required in the base mod when sculk sensors are added.

The end goal is to add cross compatibility between it and fluidlogged, but it needs to be required in the base mod.

If that's the case, perhaps you should consider adding Fluidlogged API as a required dependency? Doing so would definitely simplify things down the line. After all, the whole point of Fluidlogged API is to serve as a library for other mods to use 😄
