Turbostat currently exits under the following conditions: 1. When running on non-Intel/AMD/Hygon x86 vendors. 2. When running on Intel models that lack specific platform features. Introduce a new `--force` parameter that allows turbostat to run on these unsupported platforms with minimal default feature support. This provides users with the flexibility to gather basic information even on unsupported systems.
