feat: added ethereum address

[xlanor]

Description

Added Eth address as well as a random bitcoin (picks randomly between the 3 types avaliable). Also renamed a getBitcoinAscii to better reflect generic purpose as the same function can be used for ethereum

I am currently unable to get to 100% coverage due to the fact that some of my logic flows here are randomized (for more generic mocks like bitcoin). Would like you to take a look at my other PR after this where I addressed the underlying problem more specifically @jaswdr

[jaswdr]

LGTM, I'll merge now and fix the underlying problems in another PR
