Integrate Message Exchange (Purification/Entanglement Swapping) into RuleSet and Runtime

[Naphann]

Summary of what has changed:

1. Introduce new states for BSA to handle photons from only one side.
2. A Rule now contains send_tag and receive_tag instead of shared_tag.
3. Introduce new concepts of sequence_number
   • A sequence_number is a number assigned to each local half of Bell pairs in the order they are assigned to the Rules.
   • It is used to specify which Bell pair a message from other nodes is referring to
4. Introduce 2 new clauses and actions:
   • PurificationCorrelationClause and PurificationCorrelation(Action)
   • SwappingCorrectionClause and SwappingCorrection(Action)
5. introduce new instructions:
   • measurement and store result into specified bit-index of int
   • get/delete messages
   • get qubit by sequence_number
   • bitwise_and/or/xor
   • promote
6. simulation tests for entanglement swapping

This PR closes #98 and closes #424

unfinished tasks

• [x] rebase to make each commit self-contained and has meaning

defer to later PR

• write minimum tests for each instruction
• write tests for handling every possible case for BSA (might be in other PR)

In the following pull request, inside QRSA/HardwareMonitor/HardwareMonitor.cc, at line 835 and 840 inside "else if (purification_type == 1031)" block, it seems that the purification protocol has to be DSDA and DSDA_INV respectively in place of DSSA and DSSA_INV. Can you check on it? @Naphann @zigen @res6idue If that is so, I will make changes to it accordingly in the next pull request.
