Test core to geb translation (#1865)
This PR adds testing for the core-to-geb translation.
It works as follows:

  1. Parse the Juvix Core file.
  2. Prepare the Juvix Core node for translation to Geb.
  3. Translate the Juvix Core node to Geb.
5. Perform type checking on the translated Geb node to ensure that the
types
from the core node make sense in the Geb context and avoid any Geb
runtime
     errors.
6. Evaluate the Juvix Core node to see if it produces the expected
result.
7. Translate the result of the evaluated Juvix Core node to Geb for
comparison
     with the expected output later.
8. Compare the result of the evaluation of the Geb term produced in step
3
with the result of the evaluation of the Geb term produced in step 6 to
     ensure consistency.
9. If step 8 succeeds, then compare the output of step 6 (the evaluation
of the core
     node) with the expected output (given in Geb format) to ensure that
     the program is functioning as intended.
