Merge branch 'amanzano/37-refactor-library-rpc-implementation-of-admire-update_adhoc_storage' into 'main'

Resolve "Refactor library RPC implementation of `admire::update_adhoc_storage`"

This MR moves the implementation of the RPC construction for 
`ADM_update_adhoc_storage` to `admire::detail` in `impl.[ch]pp` 
similarly to other RPCs already refactored. This includes changing 
the C ADM_types to native C++ types.

Closes #37
