fix(zseri/store-ref-scanner): no_std support and runtime panics r/3385
This also changes the fuzzing infrastructure from proptest to cargo-fuzz,
and this lead to the discovery of two mishandlings of edge-cases:

* when a "path_to_store" is at the end of the input, it tried to access
  the input slice out-of-bounds (the `just_store` test covers that now)
* non-ASCII characters lead to an out-of-bounds access in HalfBytesMask
  (the `non_ascii` test covers that now)
