Closes #3186

This work has been co-authored with @thdaraujo

The following generators require OpenSSL:

• Crypto
• Blockchain::Tezos
• Blockchain::Bitcoin

The profiler screenshots show that loading faker spent about 9% of the samples doing that:

vernier run -- ruby -e 'load("/Users/stefannibrasil/projects/faker/lib/faker.rb")'

benchmark

CI: took 125.20560900000532ms to load

We tried requiring 'openssl/digest' only but we still needed to require 'openssl' somewhere else.

The next step was testing autoloading OpenSSL.

Autoload OpenSSL

CI: took 80.12221799998542ms to load

require 'benchmark/ips'

Benchmark.ips do |x|
  x.report('autoload openssl') { system('AUTOLOAD=1 ruby load_faker.rb') }
  x.report('require openssl') { system('ruby load_faker.rb') }

  x.compare!(order: :baseline)
end

Warming up --------------------------------------
     require openssl     1.000 i/100ms
    autoload openssl     1.000 i/100ms
Calculating -------------------------------------
     require openssl     10.485 (± 0.0%) i/s   (95.37 ms/i) -     53.000 in   5.057875s
    autoload openssl     12.429 (± 0.0%) i/s   (80.46 ms/i) -     63.000 in   5.072235s

Comparison:
     require openssl:       10.5 i/s
    autoload openssl:       12.4 i/s - 1.19x  faster

Autoloading OpenSSL is ~19% faster 🚀
