NSC_BUILDER v0.6.c

1.- Added nut options. Copy function with or without deltas. It'll let you skip the deltas wich are not needed for xci files.

For nsp files they serve to transform old updates into new ones so they install faster and old update doesn't stay in your system
They're dissabled by default if you use nsp consider activating them.

2.- Added direct extraction from xci files instead of using hactool so now extraction speed is linked to buffer.

3.- Added a couple of fallbacks to detect masterkeyrev in non standard ticket formats and old ticket formats.

4.- Minor code clean up and little fixes.

Note: Missed erasing a pause in manual-individual mode. This one fixes that.
