Please add a converter for AmkMcAuth

Describe the solution you'd like
/AuthMe converter AmkMcAuth

Describe alternatives you've considered
AmkMxAuth uses sha512 rehashed 25 times as their algorithm which isn't supported in authme. I could try to convert the 300 users to AuthMe database format if such a hash was supported in AuthMe. I saw about the custom hash in authme but i dont know how that's done.

Additional context
AmkMcAuth has a folder named userdata in the plugin folder which has files named as UUID.json with hashes stored there. Image enclosed below.
