Time for a new hactool release :)

Compilation is still annoying, so a pre-compiled build is provided for Windows users.

Since the last release, the following bugs were fixed:
-Update extraction support should no longer cause errors.
-NPDM JSON output has been switched over to the new format.
-6.x keydata will no longer be called "Unknown".

The following Switch file formats are supported:
-Package1 (PK11)
-Package2 (PK21)

Keydata can be baked in at compile-time, or loaded from an external key file. See README.md and KEYS.md for details. In addition, a secure boot key + TSEC key + boot0 file pair can be passed in with an external key file to derive all keys it is possible to know given the information one has.
