Porting the line ID tool from tardisanalysis

[jamesgillanders]

This PR moves the tardis_line_id tool across from tardisanalysis to the main TARDIS repository. The TARDIS line ID tool was originally written by @unoebauer.

Description Code has been updated to work with the newest version of TARDIS, but behaves as before.

The tool can be used to extract a list of the N most prominent transitions (default has N = 20) within a user-specified wavelength range (default is the entire wavelength range of the simulation). This can be particularly helpful for diagnosing the species with the largest contribution within a wavelength range, which perhaps has a blend of different absorption features.

Motivation and context This PR simply relocates the old tool, and makes it compatible with the new version of TARDIS.

How has this been tested?

• [ ] Testing pipeline.
• [x] Other. Ran the tardis_example.yml on the old and new versions. Output plots were similar.

Examples Here is the output plot from the old tool:

test_line_ID_K2.pdf

And here is the new version:

test_output.pdf

Type of change

• [ ] Bug fix.
• [x] New feature.
• [ ] Breaking change.
• [ ] None of the above.

I moved this tool and the opacities.py tool to a folder titled 'analysis_tools' - that's why 2 new files are appearing instead of 1

I will revisit this soon and try to get it to a merge-able state

@jamesgillanders can this still be fixed up to merge?
