Send public v5 spot sub args in batches of 10

[Tiago]

• Currently implemented for v3 spot
• V5 spot uses the shared v5 market, but a unique endpoint
• This needs to be split into batches of 10: https://github.com/tiagosiebler/bybit-api/blob/master/src/websocket-client.ts#L162

Existing implementation isn't plug-n-play since the market is v5, even for non-spot public topics. Need another way of providing a more granular check when market is v5. Look at how subscribeV5 passes in the api group.
