Expand description
Bounds-checked little-endian integer readers.
Registry hives are untrusted, attacker-controllable input. These helpers
read fixed-width integers without ever panicking on a crafted offset/length:
an out-of-range read yields 0 rather than an out-of-bounds slice panic.
Using them (instead of data[a..b].try_into().unwrap()) keeps the parser
panic-free even if a future change breaks a caller’s bounds guard — the
defence-in-depth the Paranoid-Gatekeeper standard requires.
