Update Hackney version

[perrycate]

Per benoitc/hackney#591, hackney 1.15.2 fixes
the "honor_cipher_order' issue present when sending https requests on
OTP 22.1

@perrycate, thanks for the PR! Would you mind including the requirement to be greater than 1.15.2 just so people don't try to use 1.15.1 for example (unless they override ofc)?

Something like "~> 1.15 and >= 1.15.2" I think?

[edgurgel]

Sorry @perrycate , but simply using >= will accept 2.0 for example which we don't necessarily want. That's why I proposed "~> 1.15 and >= 1.15.2" so that it will still respect ~>

[perrycate]

Oooh I see. Sorry, I'm still learning the syntax, I didn't realize 'and' was a valid keyword. Will fix in a moment, and thanks for explaining it to me!

@perrycate no worries! It's pretty impressive what it can do: https://hexdocs.pm/elixir/Version.html 🎉
