3LEB128 decoding exactly as the WebAssembly binary format defines it (spec §5.2.2): unsigned and
4signed readers for any width up to 64 bits (u32, u64, s32, s33 for block types, s64). Each returns the
5bytes it used, or 0 for a truncated encoding, one longer than ceil(N/7) bytes, or a last byte whose
6unused bits aren't zero (unsigned) or the sign (signed). Header-only and freestanding.

9replaces wasmtime in the port of alpha-rust-mesh's `mesh-host/src/wasm.rs` (wasmparser did this there).
