reworked project structure

[Icekey]

• Tesseract output gets captured directly instead of parsing it from a file
• added TSV output

Hi,

thanks for reworking the project structure!

I'm getting the following errors when I run it:

`

Are you using an old rust version? The function "get_args" is stable since 1.57.0. I always use the newest version of rust so i did not notice. What version should the libary target?

Oh yeah, thanks, might be my current version. I'll update and review the PR asap.

Thank you for merging. If you have suggestions please let me know. I am pretty much done with the rework. Only thing i feel that could be better is the error messaging and documentation of the crate with a https://docs.rs/ site like https://docs.rs/image/0.24.6/image/.
