Compliance test case failures

[brandonchinn178]

As of Jan 28 2025, kdl-rs fails the following test cases:

• Should pass
  • https://github.com/kdl-org/kdl/blob/main/tests/test_cases/input/zero_space_before_slashdash_arg.kdl
  • https://github.com/kdl-org/kdl/blob/main/tests/test_cases/input/zero_space_before_slashdash_children.kdl
  • https://github.com/kdl-org/kdl/blob/main/tests/test_cases/input/zero_space_before_slashdash_prop.kdl
• Should fail
  • https://github.com/kdl-org/kdl/blob/main/tests/test_cases/input/multiline_raw_string_single_line_err_fail.kdl
  • https://github.com/kdl-org/kdl/blob/main/tests/test_cases/input/unicode_delete_fail.kdl

The "should pass" tests don't exist in this repo; they were added Jan 28 2025. The "should fail" tests do exist, but it doesn't look like they're actually checked in validate_res:
