- Extend `pdfioArrayCreateColorFromStandard` to support CMYK.

- Reworked Widths array compression for CID fonts to require at least 4 repeated
  widths.

4165cd23ba Fix some issues discovered by some PDF checking tools: 
- Extremely small floating point numbers would be written with exponential
  notation my the pdfioContent functions.  They are now written with up to 6
  decimal places of precision with excess trailing 0's removed.
- 8-bit (simple) TrueType fonts were embedded without a Widths array, which
  made Acrobat Reader sad but nobody else...
- Switched to using the WinANSI base encoding, which is CP1252.
