fix: update target rules

[Agustindeleon]

what

• add parser events to support tags and messages enclosed in quotes.
• add support to replaced targets as stated in the Reference Manual
• separate events for each update target rule type

why

• quoted strings break the parser in update target rules
• the parser didn't support explicitly replacing targets, it only supported append target use cases
• separate events enable listener to handle each rule type differently

Maybe use updated instead or remplaced? I don't think that one exists? Maybe even new?

[Agustindeleon]

Uh, you're right. Now that you've pointed it out, it's really confusing, because the variable being replaced is actually the other one, e.g., in !REQUEST_FILENAME|REQUEST_URI, the replaced var is REQUEST_FILENAME.
updated confuses me too, I think new_target is a better option.
