add new option to hicup2juicer + keep read name

[lldelisle]

Note: This PR has more commits as development is behind master.

This PR proposes 2 changes:

• First keep the read name instead of an index
• Then, propose an option to write to OUT without storing and sorting. This is super useful when working with large experiments.

Hi,

Thanks for that!

To keep output files small could we:

1) keep the read name instead of an index - make this an option, but the default is to use the index number

Also, please could we remove those 2 new datafiles that have been added to the repo.

Thanks, Steven

Sure I can implement it. For the 2 files I added, one is already in the master branch. The second one I added it because I use it in the CI...

Maybe you can merge master in development so you better see my changes.
