Lua translation!

The kata description should state what keycap emojis are, so the user can look for their codes in the kata description instead of digging through the specification.

Missing fixed tests that check for solutions that only check that each line and block has sum 45.

aka this solution should not pass: https://www.codewars.com/kata/reviews/63d317f5d71133047010a3e3/groups/63ddccee4084800001fafe59

The random test feedback is completely useless at pointing out how the actual results are wrong. e.g Tests will give these messages:

Task going to work for 1700ms.
Task going to work for 500ms.
Task exited after approx. 500ms.
Task going to work for 900ms.
Task exited after approx. 900ms.
Task going to work for 1100ms.
Task exited after approx. 1700ms.
Task going to work for 1500ms.
Task exited after approx. 1100ms.
Task exited after approx. 1500ms.
Task [MyTaskFactory] is failing after approx. 101ms of work.
Task going to work for 700ms.
Task going to work for 1300ms.
Task exited after approx. 700ms.
Task [MyTaskFactory] is failing after approx. 2247ms of work.
Task [MyTaskFactory] is failing after approx. 2792ms of work.
Task exited after approx. 1300ms.
Task [MyTaskFactory] is failing after approx. 1200ms of work.
Task [MyTaskFactory] is failing after approx. 696ms of work.

Test Failed
  Successful tasks mismatch
  Expected and actual are both <System.Collections.Generic.List`1[Worker+Runnable]> with 7 elements
  Values differ at index [1]
  Expected: <Worker+Runnable>
  But was:  <Worker+Runnable>

It's impossible to decipher anything from this mess.
