Allow installation of large Wasm modules

I’ve seen a few solutions specifically for Wasm modules. I know @skilesare came up with one.

This is the other one I saw by @simdi.jinkins.

Issues and Solutions

1. Large binary from in-lining wasm via include_bytes!:
   Wasm code for creating new canisters is added in heap memory at runtime via an init_wasm operation. I’ve created wasm_uploader for this.
2. Payload size too large for init_wasm operation:
   The wasm binary is chunked and sent one at a time.
