feat: spec.generateContractClient; AssembledTx

- new e2e tests copied from cli `ts-tests` for the generated bindings, but
  with TypeScript removed because the ContractClient is generated here
  dynamically at run time, so we cannot know the types at compile time in
  the tests.
- generate JSON specs from local .wasm files during initiaze.sh instead
  of generating TS bindings. As explained in the new wasms/specs/README,
  this is a bummer, but is temporary
