• Changed mock() to no longer use recursive types. Only deepMock() does that now. This should reduce the tsc compile time for large projects.
• Added stub() for usecases where you need a mock object with no expectations.
• Added support for Jest 27, although blocked by jestjs/jest#11677

Potential backwards compatibility issues for use of mock() where deepMock() may be required. This may result in TS errors.
