TST: check that visualising works

[Vini2]

Look into using pillow to

• [ ] check that the output format is correct
• [ ] check that the file is consistent with the declared output
• [ ] generate both png and jpeg
• [ ] update the pyproject.toml to include pillow in the testing dependencies
• [ ] pin the pillow version
• [ ] Can pillow extract other information from the file that's useful for testing? e.g. pixels, size in bytes, etc.

File name: test_visualise.py Function name: test_generate_images

Inputs: file names in the tests/data/5G_metaSPAdes directory.

• initial: metacoag_res.csv
• final: graphbin_res.csv
• graph: assembly_graph_with_scaffolds.gfa
• contigs: contigs.fasta
• paths: contigs.paths
• imgtype: png

How to invoke:

gbintk visualise --assembler spades --initial {initial} --final {final} --graph {graph} --contigs {contigs} --paths {paths} --imgtype {imgtype} --output {outpath}

Hey @Vini2, I'll be happy to give this a go!
