Scan photos of specific directory

[tetebueno]

I've been getting memory exhaustion when scanning all photos collection on an initial load; trying to address #525 I made these changes and was able to scan each year/month directory of photos succesfully like this (the example is for the folder with photos of july '84):

$ docker exec -t -u www-data container-name php occ maps:scan-photos -vvv username Photos/1984/06

I didn't like the ifs all over the implementation, but it's something like a make it work approach. If I can get comments about it, we can make it better.

Cheers.

Thanks for your contribution. Can you pass the path as optional argument? Do you need help to fix the DCO?

[tetebueno]

You are very welcome.

Done with DCO, thanks.

Is there anything else besides this so the path parameter is optional? I believe it already is since help command displays it like this: ... [<user_id> [<path>]].

@tetebueno Do you think you will make the changes befor the NC29 release. Then I would wait with https://github.com/nextcloud/maps/pull/1244 to include this.

I'm sorry that it is on such short notice after not reviewing for a month. Just have to decide whether to wait or not.
