Adjust for OTP 24 deprecation of Crypto functions

[dbernheisel]

Sames solution as #22 but moved to compile time, and fixes an Elixir 1.12 warning as well about using :public_key without it being in the application list.

EDIT: dropped the public_key change since that has since been fixed

I'm unsure if :crypto should be added to the applications list. Elixir 1.12 doesn't complain, and tests pass, but it's definitely used. Any advice there would be appreciated.

EDIT: Nevermind! Seems to be fixed by this PR that's merged: #18

[lobo-tuerto]

@dbernheisel Any plans on cutting a release with this change in? 🤔 🙏

[dbernheisel]

@lobo-tuerto I'm not a maintainer so I don't push releases, but I'm sure that lexmag is aware.

[lexmag]

Thank you @dbernheisel.

I just released v1.2.0 that contains this change.
