spdlog: update to 1.10.0.

    Bump fmt to version 8.1.1.
    Added file event handlers #2165, #2169 Thanks @seker.
    You can get callbacks from spdlog before/after log file has been opened or \ 
closed.
    This is useful for cleanup procedures or for adding something to the \ 
start/end of the log files.

log files. #2261. (thanks @kishorekrd for reporting).
