Relax base64 dependency to allow 0.2.x

[teenu4]

monopay-ruby only calls Base64.decode64, an API unchanged between base64 0.1.x and 0.2.x. The tight ~> 0.1.1 pin blocks upgrading kamal (which requires base64 ~> 0.2) in apps that depend on both gems.

Hello, that's a good point, thanks for contribution. I will merge it when CI become green

@teenu4 looks like you have to run bundle install after changing dependencies

Hi @loqimean, you're right, my bad 🙂
I ran bundle install so Gemfile.lock is updated now, please review when you have a chance.
Thanks!
