SHA-256 signature support

[Ziyann]

I'm trying to use this applet for passing the Android 12+ CTS tests, which need an SHA-256 signature: https://source.android.com/docs/core/connect/uicc#rules_on_uicc.

However, this applet only support SHA-1 signatures. Would it be possible to add support for SHA-256 signatures?

I've patched applet to support 32-byte hash a while ago https://github.com/z3ntu/aram-applet/commits/patches/

But the problem for Android still is that the applet doesn't support PERM-AR-DO structure which is needed by Android, I haven't made a solution for this yet but probably can be patched into the applet.
