Add LFC threshold tests for DESeq2

[mikelove]

hi Stefano,

I've added examples and tests, and I tested locally to make sure that the bulk methods are still working.

I had already added in the ellipses, but I had forgotten one spot which is why it wasn't working, this PR should include all the necessary ellipses for limma and deseq2

@mikelove it seems an example is erroring

I’ll fix this

[mikelove]

Ok this latest commit should fix things

Thanks a lot for your contribution, and welcome to the tidybulk team! ;)

I have some ideas about exploring isoform-level abundance, especially within genes, do you have anything currently for this?

Nope, you have carte blanche!
