Error spam when discord is not available

[ttermeer-reboundcg]

When Discord is not running, RpcConnection is actively trying to connect repeatedly causing errors to be reported.

On .Net :

Exception thrown: 'System.TimeoutException' in System.Core.dll
Failed connection to discord-ipc-0. The operation has timed out.
Tried to close a already closed pipe.
Exception thrown: 'System.TimeoutException' in System.Core.dll
Failed connection to discord-ipc-1. The operation has timed out.
Tried to close a already closed pipe.
Exception thrown: 'System.TimeoutException' in System.Core.dll
Failed connection to discord-ipc-2. The operation has timed out.

On Unity :

Failed: Lachee.IO.Exceptions.NamedPipeOpenException, An exception has occured while trying to open the pipe. Error Code: 2
Failed: Lachee.IO.Exceptions.NamedPipeOpenException, An exception has occured while trying to open the pipe. Error Code: 2
[...]
Failed: Lachee.IO.Exceptions.NamedPipeOpenException, An exception has occured while trying to open the pipe. Error Code: 2
Failed to connect for some reason.

Either the error should be only reported once or allow us to specify a max retry count to stop the RpcConnection from connecting endlessly

It will attempt to connect on any of the 10 pipes Discord maybe available on.
If you wish to handle this logging, you can do so by writting a custom logger.

It is an exception it caught, so it needs to be logged as such
