Actually change SVG font to "Arimo, Arial, sans-serif" ([607e4ed])

Allow `--embedfont` for non-EAN/UPC SVG also (& update GUI)
SVG: add "fonts/normal_woff2.h"; use array syntax for it &
  "fonts/upcean_woff2.h" to avoid large strings
GUI: embed Arimo (via "fonts/normal_ttf.h"), same as OCRB
Change textgap max 5X -> 10X
README: make list of barcodes 2-col table for readability
win32/README: note Visual Studio 2022 re CMake
