Deprecate asset_dir variable and remove docs

* Remove docs for the `asset_dir` variable and deprecate
it in CHANGES. It will be removed in an upcoming release
* Typhoon v1.17.0 introduced a new mechanism for managing

writing out to disk. `asset_dir` became optional and
defaulted to being unset / off (recommended)
