fix(#161)!: fixed broken pipe (#178)

fixes #161

BREAKING CHANGE: --input argument  replaced by positional "content" argument.

New usage:

```
nitrodigest <file/directory/string>
```

instead of

```
nitrodigest --input <file/directory>
```

Updated main.py file to support new positional argument and support input from pipe.

Also I updated documentation and removed all --input argument occurances.
