Version 3.1.0 (1st December 2023)

• Added MSWindows USB uninstaller and libwdi based installer installer to make use on MSWindows easier.
• Added UbsDk MSWindows usb driver support code, but it is currently disabled because the release versions of UsbDk have limited usefulness as a general USB driver.
• Fixed bug in CMYK profile B2A table creation that sometimes resulted in bumpy black generation. (Only occurred when compiled using recent gcc with code optimization.)
• Changed ICC profile serialization of pure ASCII text tags emit a warning rather than error if they are fed non-ASCII utf8 input.
  Made ICC code a little more robust against bad profiles. (Thanks to David Hoyt).
• Fixed latent bug in X11 plot code that caused window not to be created or updated when dowait == 0. This shows up on Linux as failure of spotread -S to show spectral plot.
• Fixed problem with colorhug not noticing errors from the instrument.
• Updated scanin/it8Wolf.cht to improve accuracy of grey wedge patch recognition.
• Merged some Debian patches, including spelling fixes.
