Description
Currently, a small timeout ([`time.sleep(0.01)`](https://github.com/lowRISC/ot-sca/blob/e20ffa3f0210cf8b568d6bae89f59e1b6587bcf3/capture/lib/ot_communication.py#L43)) between uJSON commands are needed to prevent that the receive buffers overflow and the message gets lost.
To speed up capture rate, we should get rid of this problem.

Research direction
Start in capture/lib/ot_communication.py at the time.sleep(0.01) between uJSON commands and inspect how receive buffers are handled. Reproduce the lost-message or overflow behavior, then verify that removing the delay maintains reliable command handling while improving capture rate.
