Directories not displayed: 'gitignoring' by default may be misleading

[lucaspar]

I was thrown off to think this was an erdtree bug before discovering this behavior. I was getting this output:

$ erd --sort name --hidden --suppress-size --layout inverted data/
 data
 ├─ cplatform
 └─ zookeeper

2 directories

As opposed to something like

$ /usr/bin/tree data/
data/
|-- cplatform
|   |-- data
|   `-- logs
`-- zookeeper
    |-- data
    `-- logs

6 directories, 0 files

I propose adding a count of "ignored" locations at the bottom:

$ erd --sort name --hidden --suppress-size --layout inverted data/
 data
 ├─ cplatform
 └─ zookeeper

2 directories, 4 directories ignored

And/or a visual indication that items are omitted:

$ erd --sort name --hidden --suppress-size --layout inverted data/
 data
 ├─ cplatform*
 └─ zookeeper*

2 directories, 4 directories ignored*
