Hello

I asked "why changing the name" because (OK, I'm the author of some, but
not all) :
- On Fedora/EPEL : it is lark-parser
https://src.fedoraproject.org/rpms/python-lark-parser
- On gentoo : it is lark-parser
https://github.com/gentoo/gentoo/tree/master/dev-python/lark-parser
- On Arch Linux : it is lark-parser
https://www.archlinux.org/packages/community/any/python-lark-parser/
- On OpenSuse : it is lark-parser
https://software.opensuse.org/package/python-lark-parser

After that, I understand all arguments. I let you choose the final name. In
the end, the most important is to be able to do "import lark" :)

Regards

Thomas
