This adds the ability to access information about the current connection.
A new class was created to wrap the struct ble_gap_conn_desc with methods to retrieve the connection information.
Example server use:
```
for(auto i=0; i<pServer->getConnectedCount();i++) {
NimBLEConnInfo connInfo = pServer->getPeerInfo(i);
printf("Connected client %d info:\n", i);
printf("Peer address: %s\n", connInfo.getAddress().toString().c_str());
printf("Peer ID address: %s\n", connInfo.getIdAddress().toString().c_str());
printf("Handle: %u\n", connInfo.getConnHandle());
printf("Interval: %u\n", connInfo.getConnInterval());
printf("Timeout: %u\n", connInfo.getConnTimeout());
printf("Latency: %u\n", connInfo.getConnLatency());
printf("MTU: %u\n", connInfo.getMTU());
printf("Master: %s\n", connInfo.isMaster()? "true":"false");
printf("Slave: %s\n", connInfo.isSlave()? "true":"false");
printf("Bonded: %s\n", connInfo.isBonded()? "true":"false");
printf("Authenticated: %s\n", connInfo.isAuthenticated()? "true":"false");
printf("Encrypted: %s\n", connInfo.isEncrypted()? "true":"false");
printf("Encryption Key Size: %u\n", connInfo.getSecKeySize());
}
```
Example client use:
```
if (pClient->isConnected()) {
NimBLEConnInfo connInfo = pClient->getConnInfo();
printf("Connection info:\n");
printf("Peer address: %s\n", connInfo.getAddress().toString().c_str());
printf("Peer ID address: %s\n", connInfo.getIdAddress().toString().c_str());
printf("Handle: %u\n", connInfo.getConnHandle());
printf("Interval: %u\n", connInfo.getConnInterval());
printf("Timeout: %u\n", connInfo.getConnTimeout());
printf("Latency: %u\n", connInfo.getConnLatency());
printf("MTU: %u\n", connInfo.getMTU());
printf("Master: %s\n", connInfo.isMaster()? "true":"false");
printf("Slave: %s\n", connInfo.isSlave()? "true":"false");
printf("Bonded: %s\n", connInfo.isBonded()? "true":"false");
printf("Authenticated: %s\n", connInfo.isAuthenticated()? "true":"false");
printf("Encrypted: %s\n", connInfo.isEncrypted()? "true":"false");
printf("Encryption Key Size: %u\n", connInfo.getSecKeySize());
}
```
