Subject: [PATCH 5/9] rewrote ts config parsing using ts functions (required)

Instead of manually marging objects to form compiler options, TS API requires using built-in functions to properly resolve the config into a compiler options objects, with enums, correct types, etc. Functions implemented were `parseJsonConfigFileContent` and `getParsedCommandLineOfConfigFile`
