Required methods

`fn resolve( &self, specifier: &str, referrer: &str, is_main: bool ) -> Result<ModuleSpecifier, ErrBox>`

Returns an absolute URL. When implementing an spec-complaint VM, this should be exactly the algorithm described here: https://html.spec.whatwg.org/multipage/webappapis.html#resolve-a-module-specifier

is_main can be used to resolve from current working directory or apply import map for child imports.

`fn load( &self, module_specifier: &ModuleSpecifier, maybe_referrer: Option<ModuleSpecifier>, is_dyn_import: bool ) -> Pin<Box<SourceCodeInfoFuture>>`

Given ModuleSpecifier, load its source code.

is_dyn_import can be used to check permissions or deny dynamic imports altogether.
