Goto Definition for variables about vscode-yara HOT 2 CLOSED

I need to figure out how to bound the search to the rule. Might require

1. grabbing all lines defining a rule (^rule )
2. grabbing all lines ending a rule (^}$)
3. finding nearest rule start and rule end to the symbol needing defined
4. Running doc.getText() across that range
5. Performing a similar search to what the "rule" function already has
