This change adds parity-wasm and pwasm-utils as dependencies. These deps open a way to inspect and instrument wasm binaries before execution.
Inspection is required for finding out what memory requirements the module has. Inspection is the only possible way since sandbox API doesn't expose such info to keep it's API surface small.
Instrumentation is used for injecting gas and stack height counters.
Note that gas limit is hardcoded and syscalls don't deduct gas for now.
