iOS 12 Deprecation

[apple-ihack-geek]

Lockbox/Lockbox.m:199:58 'initForWritingWithMutableData:' is deprecated: first deprecated in iOS 12.0 - Use -initRequiringSecureCoding: instead
Lockbox/Lockbox.m:214:68 'initForReadingWithData:' is deprecated: first deprecated in iOS 12.0 - Use -initForReadingFromData:error: instead

I'll probably end up fixing this myself anyway, but if someone beats me to it, all the better.

Thanks. If you are just beginning to use Lockbox, you might want to use Strongbox (also mine) instead.

Thanks, but our app has been using Lockbox for years, and it's probably less work for me to fix this issue that to switch libraries.

Then by all means, have at it. I await your pull request. 😄

Also, I am pleased to know that someone has found this library useful!
