[feature] Saving .jobf file should be optional

[skylot]

Now jadx save rename map file (*.jobf) even it is not needed. And from PR #1275 this file saved even if deobfuscation is disabled.
To fix this, an additional option should be added and .jobf file saving should be optional (i.e. disabled by default).

[skylot]

I added a new option to control how to handle deobfuscation map file, details from cli help:

  --deobf-cfg-file-mode               - set mode for handle deobfuscation map file:
                                         'read' - read if found, don't save (default)
                                         'read-or-save' - read if found, save otherwise (don't overwrite)
                                         'overwrite' - don't read, always save
                                         'ignore' - don't read and don't save

Option also available in jadx-gui preferences

So, now saving of '*.jobf' file will be disabled by default
