[david-bouyssie]

Additiona changes:

• introduce a Cargo.toml for a workspace organization
• MGF reader improved for speed
• introduce the MgfSpectrum struct containing MgfSpectrumHeader and SpectrumData (more fine-grained data representation)
• FASTA API change (configuration at reader/writer construction, allow to access the plain header)
• fix FASTA unit tests on Windows (CRLF vs LF)
• mzio-py updated to favor the use of core::Result

mzio now depends on mzcore, however since mzcore is not published yet, I'm referrencing it locally using a relative path to mzcore.
This means that mzio and mzcore repos have currently to be sibling directories on the file system (either CI or your any computer used to build this repo).

For cargo deps, you can add github dependencies (including pinning to a certain branch or commit):

[dependencies]
sage-core = { git = "https://github.com/lazear/sage.git" }
```

Very nice tip! This would avoid my hacky Python CI, to clone the repo before the build.
