Client side receive maximum

The library supports the server side receive maximum, using a weighted semaphore to ensure that we do not have more inflight messages than the server allows, there is not yet any checking in the client to ensure that if a receive maximum was set by the client the server has not broken it. Although there is a field in the client called clientInflight declared as a weighted semaphore, this might not be the best method of tracking this (perhaps just an atomic counter?)

Just wanted to note that I don't think client-side receive maximum is meaningful unless the user has manual acknowledgements enabled.
