Addressing SVG and YAML issues from #90

[DunklesArchipel]

This PR addresses the most critical issues raised in #90.

The latest not yet merged literature up to #91 are included.

You can quickly browse through a few of the 250+ files. Replacements are always identical. If you think we need any other changes let me know.

• Personally, I suggest keeping https://doi.org/ and also other instances with a http preamble, unless there is a good reason that we should not do that. With the http preamble these keys in the files become clickable in most editors, which I find very convenient.

• I would also change all filenames such that the figure identifier is always *_f1a_*. Currently, in some cases, it is only 1 or Fig1, etc..

---

Note to reviewers:

• Some of the general code has been adapted to match the new metadata scheme. Please check if there are some erroneous additions in the py and md files.
• Feel free to briefly check a few of the yaml files. I am pretty sure not all issues are resolved. We will find more mistakes, once we have a proper schema against which we can check the yaml files.

Dependencies:

• Refactor cv.entry to match new metadata scheme (see #93) #105
• Styling cv_entry.md to make it look more pleasing. #113

@DunklesArchipel there is a merge conflict now. I had a quick look but I was not sure which of the two versions we want now.

it's solved

Isn't the supplier just Merck? and Suprapur the brand name?

Anyway, I am also not sure what exactly is the meaning "supplied purity" and why this is not only called purity. And then why is the subkey "grade" needed at all. Couldn't it just be:

purity:
  value: 99.99
  unit: pct

But then it should probably not live under source.

But it also doesn't really matter. Just something I stumbled upon.

I will address this aspect in #115.
@linuxrider and I had already a number of discussions about this aspect.
We did not yet consider the brand name

[linuxrider]

Merck for example calls "Suprapur©" a grade.
Maybe our purity can hold a grade string.

@DunklesArchipel I looked randomly at some of the changes. But I didn't look at every single line. Maybe @linuxrider wants to have another quick look.

Question about the format of the dates has to be addressed before merging.
It is a string in some cases and in other it seems to be of format date (yyyy-mm-dd).
The rest of the changes look good.
