Fix collision on multiread

[archseer]

Without this fix using the same multiread in different methods would cause a collision.

e.g. I had this definition with the Rename modifier, and it caused the same rename in other unrelated methods that were using ReferenceAddresses.

								{
									ChainSpecificName: "ReferenceAddresses",
									ReadType:          config.Account,
									PDADefinition: solanacodec.PDATypeDef{
										Prefix: []byte("reference_addresses"),
									},
									OutputModifications: codec.ModifiersConfig{
										&codec.RenameModifierConfig{Fields: map[string]string{"Router": "NonceManager"}},
									},
								},
