Open File Leak

[P3TE]

Describe the bug So I was running my simulator in a stop start fashion for a while with the ROS_TCP_Endpoint running in the background and after a while I noticed some additional errors in the console: [ERROR] [1652857378.828228]: Exception: [Errno 24] Too many open files

To Reproduce Steps to reproduce the behavior:

Environment (please complete the following information, where applicable):

• Unity Version: [e.g. Unity 2021.2.18f1]
• Unity machine OS + version: [e.g. Ubuntu 18.04]
• ROS machine OS + version: [e.g. Ubuntu 18.04, ROS Melodic]
• ROS–Unity communication: [e.g. Bare Metal]
• Branch or version: [e.g. v idk lol probably a little old]

Additional context It's possible that it's been encountered before and been fixed (I am a little behind on the version at the moment). What I might do is update my version of ROS_TCP_Connector and ROS_TCP_Endpoint and see if I can still replicate the issue.
