Add CLI

[vagenas]

It would be helpful to have a Docling CLI as a no-code conversion shortcut, also making Docling accessible to non-Python users.

Possible usage

# default could be Markdown export
docling /path/to/my.pdf  

# specifying export type
docling --to-json /path/to/my.pdf

# enabling ocr
docling --ocr /path/to/my.pdf

# specifying output location
docling --out output.md /path/to/my.pdf

# using a local folder
docling /path/to/inputdir

# using a URL
docling https://arxiv.org/pdf/2408.09869

Implementation notes

A standard library for CLI implementation is Typer.

Also, (if possible)

docling --to-json --tables-only /path/to/foo.pdf
