[BUG] Stalls/Crashes in some cases using OpenBench runs

We may need to implement multiple threads to be able to respond to command line input while searching in case stop or isready is sent.

After further investigation, it seems that I'm able to recreate crashes and stalls with other, more established engines too. This may be due to a bug or issue with how I have build cutechess-cli for use with Open Bench since Open Bench does not provide cutechess-ob for MacOS.

After messaging the Open Bench discord, it seems Andy maintains his own fork of cutechess: https://github.com/AndyGrant/cutechess

We should try building from that and see if it addresses the issues. We can possibly contribute that binary as well and add more formal support for MacOS.

We could also try out this binary: https://github.com/ppigazzini/static-cutechess-cli/releases/tag/v1.3.1
