Sleigh-lifter will lift past the end of the provided bytes

[2over12]

We should probably check the length of the lifted instruction to make sure we arent reading bytes from the 0 fill

sleigh/extra-tools/sleigh-lift/src/main.cpp

Line 72 in b3669ea

ptr[i] = 0;

ie. ./extra-tools/sleigh-lift/sleigh-lift disassemble ARM7_le.sla 002C -p ./specfiles should not print:
0x00000000: andeq r2,r0,r0, lsl #0x18

and should probably present an error like "not enough bytes"

For users who are not aware of how fills work on the backend/context registers etc the current behavior is non-obvious

Had a quick look at this today but I think it'll require a bit more thought. Even in the normal case where we've provided sufficient instruction data, Sleigh calls loadFill with a size argument past the end of the image buffer.

I suspect that's not a bug on our end but rather that's how Sleigh expects LoadImage implementations to work since the implementations that I can spot in Ghidra seem to have this zero-fill behaviour.
