Update PeanutButter.EasyArgs to be AOT-friendly

[fluffynuts]

Expected Behavior

I'd like to be able to compile cli apps AOT, and use PeanutButter.EasyArgs because it's easy!

Actual Behavior

I can't, because under the hood, EasyArgs uses the DuckTyper, which emits code - which isn't supported on AOT targets

Steps to Reproduce the Problem

1. Build a CLI app using EasyArgs AOT
2. Attempt to run
3. 💥

Specifications

• Platform: All
• PeanutButter Component: EasyARgs
• PeanutButter Version: current
