feat: saved messages

[Bugs5382]

If messages are being queued because the server is offline, we could ruin the risk of the node process that running this to go offline if it runs out of memory.

So we need to be able to set:

• Max Messages (10000) should be hard-coded limit if memory stored

• Save it to a File

Saving it to a file will create a file of all the MSH segments (maybe in an enclosed FSH or BSH segment.) so that it can be executed. The file name will have the time and date in the filename so that they are executed in order.

• Save it to a a customized service, RabbitMQ Broker or REDDIS

The RabbitMQ or REDDIS are not implemented in the package, but a function must be passed on from your app that would do that logic. saveRetrievalFunc.

If the Client class property is set to restoreMessages: true it will execute the storedRetrievalFunc handler that handles the logic from the client perpective that will get the messages and send out anything that is queue out.
