[next-major] Remove traces of CamelCase

[rgaudin]

As libzim uses CamelCase, we sometimes followed the convention to stick to the pure-wrapper way. Given case is not that important and we don't follow it everywhere (it's become minor overtime), we should just remove the remaining traces and use snake case everywhere.

It's a tiny change but obviously breaks the API so should not be merged until approaching next major release

There are also some traces of Pascal case, is it better to change them to snake case too?

Also sir i think removing camelcases from setup file is good

@siddheshwar-9897 as you can see, there is already a PR (#212) linked to this ticket which only awaits a new major release. If you think there are additional incorrect CamelCase usage, please expose them here.
