How is the buffer overflow management strategy implemented in SharedFlow?

In SharedFlow, the buffer overflow management strategy is determined by the onBufferOverflow parameter. It defines what happens when the buffer is full and a new emission arrives:

• SUSPEND (default) — the emission is suspended until there is space in the buffer.
• DROP_OLDEST — when a new element is added, the oldest one in the buffer is removed to make space.
• DROP_LATEST — the new element is discarded if the buffer is full.

This allows controlling the behavior during high emission rates and limited buffer size, preventing blocking or data loss depending on the chosen strategy.
