Fix error for invalid deku_id generation on generic enum

[wcampbell0x2a]

• Add/Fixup lifetime for generated code for enum ext id finding. Lifetime __deku needs to be added to the deku_id_type, and the impl.

NOTE: I'm not sure if __deku the the best answer, and now ignoring generics is more of a problem of me fixing the problem and the time I have to fix it in a day.

See #408, this also deals with #400

lgtm, a test case would be good for this too

Added!
