Add support to set ex_best_offers_overrides and virtualise

[gmeirelless]

Hello. Thank you all for the great framework!

Please could you make available the possibility of setting the ex_best_offers_overrides settings, available on betfairlightweight.filters? I would like to set the stream parameters similar to this example using exBestOffersOverrides as well virtualise (both available on betfairlightweight.filters):

{
"id": 1,
"jsonrpc": "2.0",
"method": "SportsAPING/v1.0/listMarketBook",
"params": {
"marketIds": [
"X.XXXXXXX"
],
"priceProjection": {
"exBestOffersOverrides": {
"rollupLimit": "50",
"rollupModel": "STAKE"
},
"priceData": [
"EX_BEST_OFFERS"
],
"virtualise": "true"
}
}
}

Thank you and regards!!!

We are restricted to what betfair make available, flumine uses market/order streaming, everything that is available is integrated so I am not sure what you are asking?
