Describe the feature

Just like the player module can push/pull items to/from a player's inventory a fluid mode could fill fluid containers in a player's inventory.
This could refill empty buckets with lava/water (or other "bucketable" fluids) from the router's buffer, or refill items that use a certain type of fuel, etc.

Reasons why it should be considered

You told me on discord it's a valid candidate for an enhancement request, so here I am requesting it. :)
