ID64 v0.6b released

After a few years there's another update to the disk image conversion package. What's new?

• significantly faster write of D64 images to 1541
  
• slightly faster read and verify of D64 images
  
• new read/write/verify for D71 images on 1571
  
• cosmetic changes to D81/D1M/D2M/D4M writers.
  

Testers are wanted for checking the NTSC timing of D64 or D71 read/write/verify. It should work, but maybe not. Please report any success or failure!
