[Feature]:SDSIO-Server should terminate pyOCD in CI mode

[ReinhardKeil]

When using the new SDSIO-Server option exit-after-playback the Server should could set SDS_FLAG_TERMINATE
https://arm-software.github.io/SDS-Framework/main/SDS_API/group__SDS__Flag__Masks.html

This could output EOT (0x04) to terminate pyOCD or find another way to achieve that.

There is an example provided, but documentation is missing.

Can you explain in a few words how it works.

@ReinhardKeil, I reviewed the code again and updated the documentation. Please take a look at the updated documentation in PR #290 and let me know if the placement and context are appropriate.
