KSC 0.10-SNAPSHOT for JRE stopped displaying all error messages 
This is obviously connected with the recent major changes regarding error reporting (https://github.com/kaitai-io/kaitai_struct_compiler/commit/2851d203be30d2e66e5d4f3b9499355c94cc415a). If you try compiling an invalid KSY which fails in the precompile phase, the compiler does not generate any files or print any error message. Take this example of a KSY that uses a `type: str` but specifies no encoding:

```ksy
meta:
  id: str_no_encoding
seq:
  - id: foo
    size: 16
    type: strz
```

```console
pp@DESKTOP-MIPASSQ MINGW64 /c/temp/kaitai_struct/tests (master)
$ kaitai-struct-compiler -- --verbose all --ksc-exceptions -t all -d compiled formats/str_no_encoding.ksy
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding="UTF-8"

```

And yes, this is the full output. Only trying to generate a spec from KST for this KSY shows what's going on (but you need to create `spec/ks/str_no_encoding.kst` for it because that's how `./spec_kst_to_all` works):

```console
pp@DESKTOP-MIPASSQ MINGW64 /c/temp/kaitai_struct/tests (master)
