The WebAssembly version of the tczipper test reads/writes temporary files in the current
directory and in the TMP directory (this is the directory returned by gettempdir).
You must pre-open these directories so the wasm environment can write in it.
Using wasmtime this can be done as follows:
wasmtime --dir=. --dir=/tmp tczipper.wasm
Similarly the testsingle test needs the same 2 directories:
wasmtime --dir=. --dir=/tmp testsingle.wasm
