Interface for notifying that spdlog drops a log?

[mudream4869]

Blocking mode is dangerous for services, but when selecting overrun mode, there is a risk of losing logs.

Not sure if there is an interface (ex: pass a callback function?) when spdlog is dropping a log.

Example callback interface?:

void func(const Log& log) noexcept {
}

There is no API to notify asynchronous log drops. However, spdlog::details::thread_pool::overrun_counter() lets you know how many logs were dropped due to overruns.
