Parse bitstream header to extract Mode, Width and Device fields.
Add validation for flash programming:
- Check device matches --fpga-part parameter
- Reject passive mode (only active mode supported for flash)
This prevents flashing incorrect bitstreams that would fail to boot.
- _raw_data is now filled in configBitstreamParser
- source may be a file or a pipe
- displayHeader become a common method (configBitstreamParser)
- improve/rewrite some parser (efinixHexparser 1s -> 11ms)
