PTDM subscribes to relevant events only

[jcapona]

Main changes

Improve PTDMSubscribeClient structure by only subscribing to the events that were marked as relevant according to the dictionary passed to the initialise method. By doing this, overhead is reduced since it's not necessary to filter the received messages once they're received since now when that happens, we're 100% sure it's from an event we're interested in.

Couldn't remove the polling since this is required to stop the PTDMSubscribeClient's internal thread.
