Breaking Changes:

* Fixed a spelling mistake: "FluidTemperature.addTemperatueToTooltip" to "FluidTemperature.addTemperatureToTooltip".
    * Usually badly named methods won't be renamed, however fluid temperatures haven't been out for very long.
* Changed the requirements for ItemFilter.matches to no longer return useful results for empty stacks - instead callers are expected to handle testing for empty stacks themselves.
* Changed BiomeSourcedFluidVolume no longer extend WeightedFluidVolume<Biome>. It now extends ColouredFluidVolume instead.
* As such water no longer stores the exact biome that it was pumped from, instead it only stores the colour.

Changes:

* Updated to be compatible with minecraft 1.16.2, which is now required for the fluids module.
* Added FluidWorldUtil.fill, for placing fluid volumes into the world. (Shartte)
* Added mixin's to hoppers and droppers to make them insert into LBA inventories. (Shartte)
* Added FluidAmount.MAX_BUCKETS and MIN_BUCKETS, which have a whole of Long.MAX_VALUE and MIN_VALUE, but a numerator of 0.
* Changed FluidAmount.saturated* to return MAX_BUCKETS and MIN_BUCKETS instead of MAX_VALUE as that's much more useful.
* Added ResolvableItemFilter and ResolvableFluidFilter, for filters that can be resolved into a ReadableFluidFilter.
* Fixed "FixedInventoryViewVanillaWrapper.getInvStack" copying the inventories stack when it doesn't need to.
* Added various "toMcBuffer" methods to fluid keys, volumes, and properties.
* Added FixedItemInv.insertStack and FixedItemInv.extractStack for inserting and extracting stacks from specific slots.
    * The signature is identical to ItemInvUtil.insertSingle and extractSingle, which are now deprecated.
* Allowed BlockEntities to implement AttributeProviderBlockEntity as well as blocks to also expose attributes.
* Added various methods to Attribute to map BlockEntity-based stuff (classes, attributes, BlockEntityType) to external attribute adders.
* Allowed custom fluids to use alpha in their colours, and made the default fluid renderer use it.

Bug Fixes:

* [#22] Fix a crash on dedicated servers.
* [#23] Fluids don't render in GUIs when using fabulous graphics mode.
* [#34] Downgrade sanity check crash to a warning when a mod's mixin makes Block directly implement InventoryProvider.
