v0.0.4 release

1. Enhance HFI monitor so that it can handle back-to-back HFI LPM
   hints. Previously it only handles first HFI LPM hints and ignore
   the subsequential HFI LPM hints until it exits Low Power mode.

2. Enhance HFI monitor to handle HFI hints for banned CPUs.

3. Introduce support for multiple Low Power states.
   With this, intel_lpmd can define multiple Low Power states that
   have different requirements for EPP/EPB/ITMT setting, IRQ migration,
   and task migration. And enter different Low Power state based on
   different utilization threshold.

4. Introduce support for work load type hint.
   Intel firmware is able to predict workload type and expose this hint
   to userspace. Add support to define Low Power states and switch
   between them based on workload type hint.

5. Allow change EPP during Low Power modes transition.

6. Minor fixes and cleanups.
