Fix temperature parsing for SAS drives

Added support for SAS drive temperature format "Current Drive Temperature:"
and made temperature extraction more robust by:
- Removing ^ anchor that was preventing matches with leading whitespace
- Using awk to find the first numeric value in the line
- Adding explicit SAS drive temperature format handling

Fixes: #11
