[api] switch to schema 1.0.0

[antond-weta]

Description

Updated the code to use the spectral json schema version 1.0.0.
Switched to rawtoaces_data v1.0.0.

Tests

Added tests to make sure that older schema version files still work.

Checklist:

• I have read the contribution guidelines.
• I have updated the documentation, if applicable. (Check if there is no
  need to update the documentation, for example if this is a bug fix that
  doesn't change the API.)
• I have ensured that the change is tested somewhere in the testsuite
  (adding new test cases if necessary).
• My code follows the prevailing code style of this project. If I haven't
  already run clang-format before submitting, I definitely will look at the CI
  test that runs clang-format and fix anything that it highlights as being
  nonconforming.
