Add stickers for ngsReports and extraChIPs

[smped]

I've added two folders at once. I hope that was OK

Could you please also (1) add a license to your README and (2) add your sticker to the repo's README file.

Hi Laurent. I've added a license, but I'm not sure what you mean about adding the sticker to the README. I've already linked it using html code & they appear for me like all the other READMEs I've checked. Can you please be more specific?

[lgatto]

Thanks for the license.

Could you list your two packages in https://github.com/Bioconductor/BiocStickers/blob/master/README.md.

Of course! Thank you. It's so obvious now I don't quite know how I missed it.
