PulkoMandy ea56f5e0be kernel: replace Spleen font with an enlarged version of the original KDL font
Recently we introduced Spleen as a larger font for KDL for high
resolution displays. However, it looks quite different from our original
font. I designed an enlarged version of our original font (designed by
Brian J. Swetland and also found in NewOS, LK and Fuchsia) to use
instead.

# PNG files for kernel debugger fonts.
# This makes the fonts easier to modify if you decide to do so.
#
# Convert the font to hex bytes that can be added to the corresponding .cpp files
# in src/system/kernel/debug/font{,_big}.cpp
#
# This uses the convert command from imagemagic to:
# - Store black as 1 and white as 0
# - Flip the image left-to-right (that's how our console code expects it)
# - Convert it to an uncompressed bitmap without header
# Then it uses xxd to convert it to an hexdump in the correct endianness.
