Incorrect half-carry and carry flag descriptions on 0xE8 and 0xF8 instructions

[gonzano]

Both of these instructions indicate the 16-bit half-carry and carry flags are used, but it should be the 8-bit versions.

I believe the 16-bit half-carry and carry flags are only meant to be used when two 16-bit values are added together and in both of these cases we have a 16-bit value (SP) and an 8-bit value (s8).
