Log error when server binary can't be found or loaded

[sleeyax]

Currently, there is a potential issue where the extension can be installed for an incorrect target architecture, resulting in it not functioning without any clear indication of the problem. To address this, we should implement a mechanism that logs an error to Burp's extension error log when the server binary is not found. This enhancement aims to prevent confusion by providing a clear error message in such situations.
