Relaxed mode with "ignore_errors" option (#201)

* Exlcude one more large file from tests as it gets timeout

* Add ignore_errors option on CLI

* Bump version: 3.0.0-alpha.5 → 3.0.0-alpha.29

* add new gitactions workflow to publish on test.pypi

* try publish on test.pypi attempt #2

* Bump version: 3.0.0-alpha.29 → 3.0.0-alpha.6

* undo changes in workflow made for test.pypi publish

* Python module: Add ignore_errors option in class methods

* Python module: Add ignore_errors in calling class methods from CLI

* JSON/dict format: remove slash(\) from value of closing
