Bruteforce an ethereum address to match certain pattern. By default, it finds an address
that has 6 consequent symbols in the beginning, but you can change the source code to match any
pattern you would like.
By default, the app uses 10 threads to find an address. This can also be changed in the source code.
After the address is found, the private key will be saved into a file named with address. The private
key will be in a hex format.
