libsrc/atari/system_check.s: fix MEMLO check
...
Old check forced the program's load address to be one more than
MEMLO. But MEMLO points to the first byte of usable RAM, not the last
byte of unusable RAM.
Problem found by Flashjazzcat, see https://github.com/cc65/cc65/issues/2964 .

Optimizer maintenance: reformat definitions providing more space for names

fix sp65 PCX reader: 1bpp monochrome path wrote past bitmap allocation
...
ReadPlane() already expands packed bits to one byte per pixel for
case 1 (1bpp), but the loop in ReadPCXFile treated the buffer as
still-packed bits using a mask-and-shift pattern. The for-loop also
failed to increment X, causing an infinite loop that wrote past the
allocated bitmap and triggered SIGBUS.
Fix: use the same direct L[X] indexing as the 8bpp path, matching
ReadPlane's pre-expanded output.
