upgrade to macro_magic 0.4.3 (#1832)

Browse Source 
# Description

Upgrades `macro_magic` to 0.4.3, which introduces the ability to have
`export_tokens` use the same name as the underlying item for its
auto-generated macro name. Ultimately this will allow for better dev ux
in our derive_impl feature.
