Getting number of active indices

[WurmPeter]

Hello Gergely,

Recently I had the need to be able to remove logging to file (index 2) IF EXISTS. logger::delete_logger_index needs an index, so I had to use a internal function to be able to get the number of active indices first:

loggers <- get(logger:::fallback_namespace("global"), envir = logger:::namespaces)
logger_indices <- length(loggers)

Are you open for a PR to include a little public function that just returns the number of current indices (logger_indices)? Or is it just better to change fallback_namespace so it's a public available function?

That's a good point, thanks for raising this.

I'd not expose fallback_namespace, so I'd prefer a new fn, similar to log_namespaces, and maybe call it log_indices to be consistent with that naming?

I'd appreciate if you can create a PR for that fn taking a single argument for the namespace, which is then internally passed to fallback_namespace.
