delete Encode requirement

this is not necessary anymore as in substrate we don't use
HasCompact::Type in arguments anymore
And so it allows get rid of Copy in srml-staking for example

generalize #[codec(compact)]

Prepare 2.2 release

Resolve issue + extend Compact

it is not necessar anymore

so it requires everything to be HasCompact

In order for the HasCompact::Type to be usable in substrate

Add repository and categories fields to Cargo.toml

Add no_std impl for some types
