b88facfb66 - more accurate timing for reading data using a motor speed of 300 RPM. This is 
important at boot time if the user wants to control the boot process.
  TODO:
  * implement timing for write and format commands
  * more accurate timing for seek, recalibrate and maybe others
  * raw floppy access slows down the emulation, use separate threads (???)
- irq line goes low with when reading the first result byte
- the drive status bits are only modified after reading the first result byte
- handling of floppy command 'sense interrupt status' simplified
- improved debug messages for i/o port reads and writes
