Does not type check correctly when loading from Deno

[cowboyd]

the following script:

import * as O from "npm:optics-ts/standalone"
O.prop('hi');

does not type check in Deno. It fails with the following error:

error: Uncaught Error: Error resolving package config for 'npm:optics-ts/standalone'.: [ERR_INVALID_PACKAGE_TARGET] Invalid "exports" target {"import":"./dist/mjs/standalone/index.js","require":"./dist/cjs/standalone/index.js"} defined for './standalone' in the package config /Users/cowboyd/Library/Caches/deno/npm/registry.npmjs.org/optics-ts/2.4.0package.json imported from file:///Users/cowboyd/Library/Caches/deno/npm/registry.npmjs.org/optics-ts/2.4.0/; target must start with "./"
