closes #53 dependencies bump

[DahanDv]

As written in the issue log, the support for 3.6-7 is very limiting;
hence so few version bumps are possible without running into dependencies nightmares.

@Naramsim Good to go by me.

[Naramsim]

Can you bump the version in the setup.py? And remove python 3.6 support?

[DahanDv]

Can you bump the version in the setup.py?

Sure

And remove python 3.6 support?

Do you mean the commit message? I overrode its content; I'll squash it fine? (not 100% sure I understand your intent)

Nono, I meant here:

version, bump to 1.4.0: https://github.com/PokeAPI/pokebase/blob/master/setup.py#L12

drop support: https://github.com/PokeAPI/pokebase/blob/master/setup.py#L23

[DahanDv]

Done! :D

Thanks!
