enable debugging options for Carp and Type::Tiny

[sherrardb]

i have found these to be very useful during development.

$Carp::Verbose = 1;
$Type::Tiny::DD = 999_999;

and can mean the difference between

Unknown named parameter: card at lib/Net/Stripe.pm line 2289.

and the much more useful

Unknown named parameter: card at lib/Net/Stripe/Resource.pm line 99, <DATA> line 1.

i usually just hack them in while i am working, and remove them before commit, but it might be useful to enable them dynamically based on the value of $stripe->debug.
