lualoader: Use less atomic options for resetting colors/attributes

Noted by dteske:

CSI 1m ... CSI 22m
CSI 2m ... CSI 22m
CSI 4m ... CSI 24m
CSI 5m ... CSI 25m
CSI 7m ... CSI 27m
CSI 8m ... CSI 28m
CSI (30-37)m ... CSI 39m
CSI (40-47)m ... CSI 49m

• Provide resetf/resetb to match escapef/escapeb
• Use CSI 22m to undo a bold

This is a more reasonable approach than what was previously taken.
