This will be breaking.
We can do it slightly differently:

1. Allow `org-id-method' to be a list of methods/functions to try in
   addition to being a symbol.
2. Add new customization `org-id-methods' that will link method names to
   functions: '((ts . org-id-ts) (uuid . ...) (uuidgen . ...) (org . ...)).

That way, old configurations will continue working.

Just by default. We do not constrain users from using arbitrary IDs,
including manually typed.
