[FEATURE REQUEST] Download only metadata

[lambdareader]

It would be nice to add a feature to only download metadata. For example --only-meta.
Since metadata sometimes changes (titles, tags, favorites) I redownload the metadata again every so often. It would be nice to add the option so someone doesn't have to hack the code to only download metadata (in json or comicinfo or txt like the options already are).

Although I recognize that not a lot of people may use this.
So please feel free to close this issue if it is to much work or you are not interested.
Thanks for your work!

According my test, the option --meta will re-fetch the metadata from nhentai.net and generate a new metadata file without downloading the full doujin, the re-generated metadata files including info.txt, metadata.json but not including ComicInfo.xml.

The logic of this program is, if pdf/cbz/images files exist, it will not re-download the image files.

My command is nhentai --id 558413 --output /tmp/ --format %i --meta

So let's find the real feature you want:

1. Re-generate the ComicInfo.xml
2. For some reasons, the program will re-download the full doujin, so you need this option to avoide the downloading process.
