We probably want to follow the pattern in #232 to avoid breaking the library on older releases of OTP. That is, crypto:pbkdf2_hmac is new in OTP 24 and missing from older versions, so if we run this patch on OTP 23 we'll crash for the same reason this fix exists.

My read on the docs is that it came in with OTP 24.2, with crypto 5.0.5
Come to think of it, do we need to check for 24.2 even? I guess OTP 24.0 and OTP 24.1 won't have it either. I'm not sure off-hand how to check for the minor version and I hope we can do it in the macro so this doesn't have to be a runtime check.

I couldn't find a predefined macro returns the minor/patch version
