manuelk b27b55e4a8 Refactor Far::PatchTables
- split Far::PatchDescriptor into its own class (mirrors Far::PatchParam)
- hide PatchArray as a private internal structure
- add public accessors patterned after Far::TopologyRefiner (returning Vtr::Arrays)
- propagate new API to all dependent code

note: some direct table accessors have not been removed *yet* - see code for details
