Add AE2 Cell Workbench API

[Armisael5]

Summary

Adds an API for the AE2 Cell Workbench which is compatible with Item, Fluid, and Essentia storage cells. Allows reading and editing of partition filters, type/amount restrictions, and oredict filter strings.

Includes the following methods

hasCell():boolean -- Returns whether a storage cell is currently inserted.
getCellType():string -- Returns the inserted cell's type ("item", "fluid", "essentia", ...). Returns nil if no cell is inserted.

getPartition():table -- Returns every partition slot as a table keyed by slot number (1-based). Empty slots are omitted.
setPartition(slot:number[, item:string OR table]):boolean -- Sets the partition in the given slot (1-based). Accepts a name, or a table for more detail (e.g. item damage). Omit the item to clear the slot.
clearPartitions():boolean -- Clears every partition slot on the inserted cell.

getRestriction():number, number -- Returns the cell's restriction as (types, amount). (0, 0) means unrestricted.
setRestriction(types:number, amount:number):boolean -- Sets the cell's restriction. (0, 0) means unrestricted.

getOreFilter():string -- Returns the inserted cell's ore filter string. Returns empty string (not nil) if unset.
setOreFilter(filter:string):boolean -- Sets the inserted cell's ore filter string.
