feat: add adapt option for build and test commands

[jamesstocktonj1]

Description

• Add --adapt option for both build and test commands
  • Allows developers to specify their own wasi snapshot adapter or use the default one packaged with componentize-go
• Allow wasi_snapshot_preview1.reactor.wasm to be configurable. #33

Example

Without flag:

$ componentize-go --world hello build
$ wash inspect main.wasm
package root:component;

world root {
  import wasi:io/poll@0.2.6;
  import wasi:clocks/monotonic-clock@0.2.6;
  import wasi:cli/environment@0.2.6;
  ...
}

With flag:

$ componentize-go --world hello build --adapt wasi_snapshot_preview1_v24.0.4.reactor.wasm
$ wash inspect main.wasm
package root:component;

world root {
  import wasi:io/poll@0.2.0;
  import wasi:clocks/monotonic-clock@0.2.0;
  import wasi:cli/environment@0.2.0;
  ...
}

Nit: I'd recommend using with_context instead of context here to avoid allocating and formatting the string until and unless an error occurs.
