Launch kit does not support proxy id besides ERC20 and ERC721

[JoaoCampos89]

If an SRA pull orders from mesh to their local database can get orders with proxy id's different than ERC20 and ERC721, this causes the endpoint get v2/asset_pairs to fail because mesh orders could be AssetProxyId.MultiAsset, AssetProxyId.StaticCall, AssetProxyId.ERC1155. We can solve this filtering the orders which have non-supported proxy's

public static async getAssetPairsAsync(
      page: number,
      perPage: number,
      assetDataA: string,
      assetDataB: string,
  ): Promise<PaginatedCollection<AssetPairsItem>> {
      const connection = getDBConnection();
      const signedOrderModels = (await connection.manager.find(SignedOrderModel)) as Array<
          Required<SignedOrderModel>
      ;


      const assetPairsItems: AssetPairsItem[] = signedOrderModels.map(deserializeOrder).filter(filterNonAsset).map(signedOrderToAssetPair);

using this function:

const filterNonAsset = (signedOrder: SignedOrder): boolean => {
    const assetProxyId = assetDataUtils.decodeAssetProxyId(signedOrder.makerAssetData);

    switch (assetProxyId) {
        case AssetProxyId.MultiAsset:
            return false;
        case AssetProxyId.StaticCall:
            return false;
        case AssetProxyId.ERC1155:
            return false;
        default:
           return true;
    }
};
