v1.0

• fbdoom_vec can now run on RiscV CPU that supports RVV1.0 with VLEN=256
• It leverages vrgather.vv to do COLORMAP indexing
• It leverages segment store to do scaling
• Tested on Banana Pi BPI-F3
• Attached binary is compiled with gcc 14.2.0
• Need to play in a console window (ctrl + alt + F3), and use sudo to gain write access to /dev/fb0
• Have fun!
