From 64ebcbc1e4730696fcf8384cf40ca8952fcfc0cf Mon Sep 17 00:00:00 2001

Subject: [PATCH] feat(component): wip component model support

- upgrade to wasmtime>=13, wasmtime_wasi>=13
- the component model necessitated splitting the adapter setup into two parts:
  first creating the adapter so it can be associated with the state, then telling
  the linker how to get from the incoming state to the adapter. WASI also has this
  split.
- change the c bindings in observe-api:
  1. "_" is an illegal character! switch to "-".
  2. change the module name from "dylibso_observe" to "dylibso:observe/api"
