Retryable 2.0.0 support

[oliviermilla]

Hello guys,

I updated retryable gem to version 2.0.0. This makes ocrsdk not work anymore with the following error:

NoMethodError: undefined method `retryable' for #<OCRSDK::Image:0x0000000e375740>

Reverting to version 1.3.6 makes all work again.

You should either specify the retryable version in the gemspec or add support for version 2.0.0.

Cheers, great gem! :)
