Abstract away details in `placeOrder`

[metaproph3t]

Today, it's a bit cumbersome to specify all of the fields in PlaceOrderArgs and the other fields that placeOrder takes

It would be nice to have a placeOrder interface that looks something like:

public async placeOrder(
      market: PublicKey,
      side: Side,
      priceLots: BN,
      maxBaseLots: BN,
      maxQuoteLots: BN,
      orderType: OrderType,
      expiryTimestamp: BN = new BN(0),
      selfTradeBehavior: SelfTradeBehavior = SelfTradeBehavior.DecrementTake,
      limit: number = 255,
      userTokenAccount?: PublicKey,
      clientOrderId?: BN,
   ): Promise<BN>

• openOrdersAccount could be set by a call .setOpenOrdersAccount() on the client
• the MarketAccount could be pulled either from on-chain or from a cache
• if userTokenAccount isn't provided, default could be associated token account for the user's public key
• clientId could start at 0 and increment each time, unless explicitly specified, and be returned by the function

that way, you would only need to specify 5 params instead of 15

Solved this issue in openbook, you only need 3 params:

Have a look at the ob_client module for more info about the refactor i did to the client code.
