This PR removes sp-std crate from substrate/primitives sub-directories. For now crates that have `pub use` of sp-std or export macros that would necessitate users of the macros to `extern crate alloc` have been excluded from this PR. There should be no breaking changes in this PR. --------- Co-authored-by: Koute <koute@users.noreply.github.com>
