___select_logger: combining TeeLogger with ____FilteredLogger

[oxinabox]

For each of the filtered loggers, we could define a convience select_logger as for example:

function early_select_logger(cond_func, if_true_logger::AbstractLogger, if_false_logger::AbstractLogger)
    return TeeLogger(
         EarlyFilteredLogger(cond_func, if_true_logger),
         EarlyFilteredLogger(!cond_func, if_false_logger),
     )
end

This seems like a common usecase. E.g.
