[WIP] EMBOSS v6

[shiltemann]

I will work on updating EMBOSS tools from v5 to the new v6 suite here.

We can leave this open while I add more tools, or merge whenever somebody requests one of the tools orso.

Help is welcome of course!

And just to remind myself of the most popular emboss tools to prioritize:
