chore(cli): update cli after watermarker refactor

[Schiphorst-ISST]

Description

updates the cli tool after the big watermarker refactor in #303 to use the new watermarker classes and insert RawInnamarkTags by default. As there are no automated tests for the cli I tested each command manually and recommend the reviewer do the same.
After following the installation instructions the available commands are structured as follows (since the current documentation doesn't provide details yet):

- Innamark [-t <file type>] add <watermark> <source path> [<target path>]
- Innamark [-v -t <file type>] list <source path>
- Innamark [-t <file type>] remove <source path> [<target path>]
- Innamark text add <cover string> <watermark string>
- Innamark [-v] text list <watermarked text string>
- Innamark text remove <watermarked text string>

square brackets denote optional arguments, file type can be "text" or "zip" (case insensitive)

I was able to successfully build the CLI tool on my machine. I was also able to watermark a file and extract the watermark afterward. It was also able to extract the output in the webinterface. Further, the new error messages also work.
