AppView Proxying codegen

[DavidBuchanan314]

New endpoints have been added that I need to account for. I should auto-generate appview proxying stubs based on lexicons.

@SaltyAom do you consider this for the next release? This is pretty useful. Like transforming a string to a date, converting using an enum and so on. I wonder if this is actually just a type issue or if this needs more work (actually transforming the data using typebox).

I didn't hunt down where the deserialization happens, but as long as Elysia is using Decode it should automagically work, and indeed that seems to be the case in my little project.
