Replace java-faker with kotlin-faker

[serpro69]

Hi, Since easy-random deals a lot with data generation, I thought this PR would be beneficial for this library :)

java-faker has not been well maintained lately, and has a big number of open bugs. This PR replaces java-faker with kotlin-faker, which in addition to being actively maintained, has more data providers and locales implemented and has extra "batteries" included, like generation of random class instances, unique random values, etc. It's also quite faster than java-faker.

This is my first contribution, so hope I've done everything that is required for first-time contributors.
