Encryption of decrypted mlc using wfs-reencryptor read out of file

[LittleStinky123]

I really appreciate your project, thank you very much for your work so far.
To save space when storing my mlc backup I want to compress the plain decrypted version of it to encrypt and restore it in the worst case.
So I first dumped it using minute and decrypted it using this command:
./wfs-reencryptor --input '/home/lel/wiiu2/wiiu_mlc.img' --output '/home/lel/wiiu2/wiiu_mlc_dec.img' --input-type mlc --input-otp '/home/lel/wii_u_sd/otp.bin' --input-seeprom '/home/lel/wii_u_sd/seeprom.bin' --output-type plain
I have attached the output that I receive from running it.

decryption.zip

I receive a 29.2GB file with apparently 6.36GB used.
When trying to encrypt it again using this command:
./wfs-reencryptor --input '/home/lel/wiiu2/wiiu_mlc_dec.img' --output '/home/lel/wiiu2/wiiu_mlc_reenc.img' --input-type plain --output-otp '/home/lel/wii_u_sd/otp.bin' --output-seeprom '/home/lel/wii_u_sd/seeprom.bin' --output-type mlc

I receive this output:
Exploring: 0.00 GB | 1 blocks | Exploring: transactions Error: FileDevice: Read out of file.

wfs-info is also similar:
Allocator state:
Error: FileDevice: Read out of file.

I hope this is not a duplicate of #52

Yes it seems that there is a bug with opening plain dumps. It is a simple fix so I will fix it but it does make me worried about the conversation to an encrypted dump again.
The issue is that the encryption depends on the parameters of the device (sector size, sectors count,..) as the wiiu see it. For USB it is from the parameters of the device, for MLCs it does some other calculation. So far for simplify reading dumps I could find the parameters from the encryption itself (to simplify it - see which parameters decrypt the device properly). So for creating a new image I need to know the parameters of the device.
For wfs-reencryptor to simplify it I assumed that the input device and the output device has the same parameters. But when opening a plain dump, I can't restore the parameters because it is not encrypted....
I will have to add a proper support for detecting a device, or to allow to somehow specify it in the parameters. The dumps that you take should be ok and will be usable in the future, but currently it will be problematic to reencrypt it back.

I have merged a temporary fix for that. for mlc it should work now to reencrypt back. for usb it depends on the sectors count alignment.
