Issue description: External Storage module doesn't work with Mekanism's Bins

What happens: It doesn't export the items to the bin, nor does it show the items in the network to grab from.

What you expected to happen: For it to show the items in the bin in the Grid and allow you to pull them out and put them into the bin.

Steps to reproduce:

1. Get Grid and Mekanism bin
2. Attach External Storage to Mekanism bin and configure with priority and item of desire (used sand, dirt, and cobble in this case)
3. Put item in network and it won't export to container, and if already in container, won't show in the network.

• Forge: 2076
• Refined Storage: 0.9.4

Does this issue occur on a server? [yes/no] Yes

Hi,
did you pay attention to the bins only accepting items from top and provide through bottom?

I didn't have the chance to respond to this, but yes. I did pay attention to that and it didn't help.

The bins are incompatible with RS by nature: they have different sides configured for input / output. RS needs to have both in / out access on 1 side.

So this could be fixed with some API: The deep storage unit API from MFR. Mekanism already uses this, but only if MFR is installed. And since MFR doesn't exist on 1.10.2, their DSU integration would never work.

So, this should be fixed at Mekanisms side by enabling DSU support even if MFR is not installed.
