New project "Casefy"

[dmlls]

Hi everyone. First of all I want to say that I would have preferred contributing to this project, but looking at the issues and PR, it appears it is not maintained anymore.

That is why I have decided to create the new package Casefy.

It takes a lot of inspiration from this project, and I have also kept the API as similar as possible, in order to facilitate any possible migrations. However, it includes a series of improvements and fixes, addressing all the problems stated in #2, #4, #5, #14, #16, #20, #25, #29 and #30.

As I was pretty much done with the implementation, I first knew about case-conversion. It looks like a great project and I recommend everyone to visit it. The code and scope of Casefy is more lightweight (for example, it doesn't implement a case detector since it's not really necessary, at least for most cases).

Again, I would like to thank the author of this project and all its contributors. I hope not one finds inappropriate to open this issue here, I'm just trying to help whoever might find this useful.
