fix file reads; bump version to v0.3.2 (#49)

Reading from files via e.g. `os.ReadFile` was broken due to a bug in the
`wasi_snapshot_preview1` adapter _and_ another bug in my patched version of Go.
The following PR and commit fix those issues:

- bytecodealliance/wasmtime#13111
- dicej/go@1f14282

I've updated the adapter using a build from
bytecodealliance/wasmtime@d60f178
and pointed the Go URL to the new release URL.  I've also updated the download
directory to force a new download for users which may already have the old
version.

Finally, I've updated the Go wrapper to point to the `v0.3.2` release (which
doesn't exist yet, but will soon).  Previously, we were pointing to the `canary`
release on the `main` branch, but it's annoying to switch back and forth when
tagging releases, so let's just leave it set to whatever the latest release is
for now.
