handle double-indent followed by double-outdent

The formatter should prevent multi-indent when followed by multi-outdent. In this case, we have { and function, then on another line } followed by end function

This will require a lookahead to figure out if we're doing to outdent the same number of indents.

temp = {
	key_9: { env: ["any"], themes: ["any"], runtimeCheck: function() as boolean
			return true
	end function }
	key_10: { env: ["any"], themes: ["any"], runtimeCheck: function() as boolean
			return false
	end function }
	key_11: { env: ["dev"], themes: ["any"], runtimeCheck: function() as boolean
			return true
	end function }
	key_12: { env: ["any"], themes: ["any"], runtimeCheck: function() as boolean
			return true
	end function }
}

Should be:

temp = {
	key_9: { env: ["any"], themes: ["any"], runtimeCheck: function() as boolean
		return true
	end function }
	key_10: { env: ["any"], themes: ["any"], runtimeCheck: function() as boolean
		return false
	end function }
	key_11: { env: ["dev"], themes: ["any"], runtimeCheck: function() as boolean
		return true
	end function }
	key_12: { env: ["any"], themes: ["any"], runtimeCheck: function() as boolean
		return true
	end function }
}

No files or tests are named. Start by tracing the formatter's indentation logic and the proposed lookahead around {/function followed by }/end function; done means the shown input receives the reduced indentation in each function body without incorrect multi-outdenting.
