Add distinct types for Set- and Reset-dominant Memory (add 2 classes, remove 1 class)

Instances of the class «Memory» need to carry information about which input terminal is dominant. IEC PAS 63131:2017 defines the visual distinction to be made with an underscore under the dominant terminal (ref. Table B.2 “EFB function notations”). The AML Library definition (version 0.0.8) does not contain a mechanism to carry this information about dominant terminal.

I propose to solve this by splitting “Memory” into two classes:

MemoryDominantR
MemoryDominantS
