- Instead of adding a separate module `schema` like there was before, since service parsing and executable parsing have a fair amount of overlap I put them as two submodules `executable` and `service` in both `parse` and `types`. Also, the grammar is unified under one `.pest` file. - Added const equivalents to `Value`, `Directive` etc - Change the reexport `async_graphql::Value` from `async_graphql_parser::types::Value` to `async_graphql_parser::types::ConstValue` since in 99% of cases in this library a const value is wanted instead of a value. - Added consistent usage of executable/service instead of the ambiguous query/schema. - Some of the tests actually had invalid GraphQL so the new more correct grammar made them fail, that was fixed. - Added a `Name` newtype to refer to GraphQL names (`[A-Za-z_][A-Za-z_0-9]*`) since they are used so frequently.
