BeOp Bid Adapter : update keywords management (prebid#9166)

* Don't know why params are in an array in that bid object. Make it work for both if it is fixed later

* Update params reading method to adapt to arrays for all params

* Keywords have to be an array of string (prebid#9)

* Keywords have to be an array of string

* Last check if isStr

* Fix linting errors

* Fix tests
