Add debugging mode

Want a debugging mode

Add a breakpoint instruction that when hit will pause execution and allow the user to run some commands on the hydro code

• [x] ~Breakpoint instruction~
• [x] Set breakpoints from debug command line
• [x] #46
• [x] view variable values
• [x] #47
• [x] view stack
• [x] #48
• [x] continue execution
• [x] dump stack trace
• [x] ~profile instruction~
• [x] step forward
• [x] #49
• [x] #50

Added ability to print the stack trace just need the debugging interface.

Step backwards will rely on recording the exact history of the ExecutionContexts. Then we can continue execution at an old ExecutionContext.

Requirements for this to work:

• [ ] Ability to continue execution from any existing ExecutionContext
• [ ] Continuing execution must act exactly the same as if we never stopped (Barring some external effects that are out of hydro's control)
• [ ] All state must be tracked in the ExecutionContext
  • [ ] random state (tracking this will let us replay the exact randomness)
  • [ ] console output

Wont make breakpoints and profile ranges their own function since it would be annoying to add them in and have to readjust jump pointer ranges
