Support for electron/fuses

[eXhumer]

Is there any consideration for supporting electron/fuses? I would like to encrypt the cookies with [FuseV1Options.EnableCookieEncryption]: true fuse with my application, but making any fuse changes causes the python -m castlabs_evs.vmp sign-pkg command to fail with the following error. It makes binary level changes to executable to flip fuses, which causes the bad signature I think.

(evs-env) PS C:\Users\eXhumer\Projects\eXViewer> python -m castlabs_evs.vmp sign-pkg .\out\eXViewer-win32-x64\
Signing: .\out\eXViewer-win32-x64\eXViewer.exe
 - Verifying existing VMP signature
 - Signature invalid: Failed to verify signature
 - Requesting VMP signature
HTTPError: Signing request failed: 400 Bad Request
 <- ValidityError: Binary signature denied

The sign-pkg command has no issues if no fuses are changed from default.

By default, the following fuses are used

(evs-env) PS C:\Users\eXhumer\Projects\eXViewer> yarn run electron-fuses read --app .\out\eXViewer-win32-x64\eXViewer.exe      yarn run v1.22.19
$ C:\Users\eXhumer\Projects\eXViewer\node_modules\.bin\electron-fuses read --app .\out\eXViewer-win32-x64\eXViewer.exe

This is actually something that would be interesting to add support for. For now it is not planned, and it is likely to be rather complicated to add safely (so I can't give an estimate or anything), but I will make sure it is put up for consideration.
