Function try_replace_all_byteset

rust/stringzilla.rs:1688–1712

Tries to replace all non-overlapping bytes in `buffer` that belong to `byteset` with `replacement`. Uses the same three-way strategy as [`try_replace_all`]. If the byteset is empty, the buffer is left untouched. Returns the number of replacements performed.
