Previous changes from v0.3.6

Hello!

The focus of this release is the pdfcpu config dir.
🔧 This dir contains config.yml which represents the current default configuration.
config.yml will be loaded on restarting pdfcpu either via the API or the CLI.

You can find out about the location of the config dir via pdfcpu version -v

👀 Since there seem to be usecases where it makes sense to bypass the config dir
you can pass the new flag -config disable into any call executed on the cmd line
and in your Go backend you may call api.DisableConfigDir() to achieve the same.
Just a friendly reminder that in such a scenario user fonts (possibly for stamping) are not available.

You can also pass a custom path to an existing directory like in config /User/pdf
and pdfcpu will create a pdfcpu config dir within. Like this you can manage multiple config dirs.
Just make sure you pass the corresponding config dir you'd like to use before your pdfcpu operation.
```
.
├── config.yml
└── fonts
    ├── Geneva.gob
    ├── OldTypewriter.gob
    └── Roboto-Regular.gob
```
The config dir also contains a dir called fonts which is the home for user fonts installed via eg. pdfcpu fonts install abc.ttf
🚀 More about this in the next release which will be all about fonts.

Thank you all for reporting bugs and filing issues.
🍱 Stay tuned and happy coding 💚
