fix(cli): make enum CLI arguments match documented format (PR #1787)

Currently if you do `jadx --help`, it says the `--deobf-cfg-file-mode` option accepts the value `read-or-save`. 

However, if you give it that option, it instead prints the following error message:

```
java.lang.IllegalArgumentException: 'read-or-save' is unknown, possible values are: read, read-or-save, overwrite, ignore

```

This commit changes all the enum parsers to do the inverse string of `enumValuesString`, so the documented behavior works.
