lint_hard

• split the document_throws code into its own package and now depend on that.
• numerous fixes to document_throws.

• added the throwing_unthrown_exception lint for @Throwing types that are not thrown.
• improved document_throws_fix handling for provenance cleanup and doc comment formatting.
• clarified plugin configuration and documentation.

• re-ordered the readme so that the install instructions are closer to the top.

• implemented new lint: document_thrown_exceptions that warns when a method has not documented a throws clause.
• migrated the code away from custom_lint to the analyzer v9 package.
• UPGRADE: if upgrading from lint_hard 6.x you will need to include a plugin declaration in your analysis_options.yaml file to activate the custom lints in lint_hard. See the README.md for details.

• disabled type_annotate_public_apis as it is incompatible wiht omit_obvious_property_types which I consider the more important lint for most users. If you are a package maintainer you should re-enable type_annotate_public_apis for your public api's.

• added custom lint 'fields_first_constructors_next' which places fields before constructors so that the state of a class is at the top and together.

• removed unsafe_variance. It's experimental and the suggested fixes seem overly complicated and you still have to suppress the warning.

• omit_obvious_property_types
• deprecated_member_use_from_same_package
• unsafe_variance

• added 3.7 lints

• removed strong mode as it is deprecaed in favour of the new
• removed implict-casts as its no longer required and has been removed in 3.x
