Version bump (v1.1.0)

Implemented Regexp#random_example !!!

This is effectively just a (MUCH) more efficient way of doing:
/complicated .{20} regex/.examples(max_group_results: 9999999999).sample(1)

Instead, you can use much more optimised code for this method via:
/complicated .{20} regex/.random_example

The key differrence being that Regexp#random_example does not store any
more than 1 result in memory, at any time, making its performance scale
linearly rather than exponentially.
