For looking at statistics over time, it is helpful to be able to
quickly query the number of unique maintainers, collaborators,
areas, and the number of orphaned areas (without a maintainer).
This change adds the `count` subcommand to
`scripts/get_maintainer.py`.
```
% python3 ./scripts/get_maintainer.py count -h
usage: get_maintainer.py count [-h] [-a] [-c] [-n] [-o]
optional arguments:
-h, --help show this help message and exit
-a, --count-areas Count the number of areas
-c, --count-collaborators
Count the number of unique collaborators
-n, --count-maintainers
Count the number of unique maintainers
-o, --count-orphaned Count the number of orphaned areas
% python3 ./scripts/get_maintainer.py count
areas: 113
maintainers: 49
collaborators: 81
orphaned: 21
% python3 ./scripts/get_maintainer.py count -o
orphaned: 21
```
