Display alignment quality

[AntonPetrov]

@blakesweeney As discussed, here is an issue describing the changes required for R2DT v1.4.

Starting from version 1.4 R2DT provides a new SVG file that is annotated by alignment quality. It would be useful to show this information in the results viewer using a toggle or a button to Hide/Show alignment quality, similar to how one can hide or show the nucleotide colours. The SVG file is named <rna_id>.enriched.svg similar to the existing <rna_id>.colored.svg files.

One could do it using 2 approaches:

1. Load the .enriched.svg file instead of the .colored.svg file and show the alignment quality by default
2. Load the .enriched.svg only if the Show alignment quality button is clicked.

I would advocate for the first approach but the second one is fine too.

I will post further information here once the new API goes live on wwwdev and the new .enriched.svg files are created.

Hi, would you like us to deploy the current version of R2DT to dev? I don't see a tagged release for v1.4, which is why I am asking.

That's a good idea, it's safe to start running the develop branch while I finalise the last few bits for the release. Thank you!
