sysutils/hexyl: update to 0.13.0

Features
 - Support both little and big Endian dumps using --endianness={little,big},
 see #189 and #104 (@RinHizakura)

Changes
 - Breaking: Changed the meaning of the short flag -C to be consistent with
 hexdump -C. Previously, this would hide the character panel, but now -C shows
 the character panel, in case it has been previously (e.g. in an alias)
 disabled with --no-characters, see #187 (@sharkdp)

hexyl as a library
 - New endianness method for PrinterBuilder
