add REST scoring function

[NoamGaash]

Goal

when the user makes several requests to the same resource, we want to distinguish state altering requests from read only request, and replay the requests in the right order. for example: GET api/status returns {"count": 123} GET api/status returns {"count": 123} POST api/status with body {"count": 456} returns {"saved": true} GET api/status returns {"count": 456}

when recording and when replaying, we want to achieve the same behavior.

usage:

    await advancedRouteFromHAR(/\/(api)|(bff)\//, {
        matcher: baseMatcher({
            scoring: restScoring
        })
    });
