Custom headers with JWT

[noobnooc]

What is the feature you are proposing?

I am building something with APN (Apple Push Notification) and it needs a token signed by JWT with some headers and payload. I noticed that the JWT related helpers in Hono do not support for custom headers but only fixed {alg, typ}, so I cannot sign the APN token with JWT helpers in Hono.

I finally implemented it by myself, it's not too complex. But I still hope to be able to implement it with Hono, it will be more convenient.
