* megascript: always inject correct sigs when installing b9s
someone just bricked by accidentally using the dev firm because there was no check for it and this was not being done
* split up sighax literal
Except for cia building or loading cia just yet.
Added more checks on ticket content index, mainly due to having effects
in the ticket format itself, and are unknown still.
Ability to determine ticket size.
Verify signature with ticket's proper size.
Changes to use the new Ticket struct with the flexible array member.
This stops certain games such as _Animal Crossing: New Leaf_, _Super Smash Bros._, and the _Pokemon_ series from erasing their saves due to changes in "Secure Value" after CTRTransfer or NAND restore.
When identifying a selected `00000001.sav`, cmac type testing is first attempted for 3DS saves with the **DISA** format. If a 3DS save data is not detected, the search continues at expected offsets for gba vc bottom slots in increasingly larger save sizes. For the GBA VC saves, this only calculates and corrects whichever of the two slots is newer or has the higher counter. There are five additional **CMAC_AGBSAVE_** types to differentiate the different gba save sizes. If a bottom slot was found but determined to be older based on comparing the counter values, the search defaults to **CMAC_AGBSAVE_SD**.
For the save counters, there are two scenarios where the value `00` is considered bigger than `FF` depending which slot has what value. If clarification is required, I will post a diagram at [issue #494](https://github.com/d0k3/GodMode9/issues/494) explaining what is meant by `00` bigger than `FF`.
Please make corrections and improvements to the coding as you see fit in your review. I am not well versed or efficient in the C/C++ programming language.
