Using # as an alias does not work

[alwyntan]

Problem

tsconfig paths are supported now #48 , but using # as an alias does not work, but other symbols like @ or $ works.

To reproduce, setup aliases in tsconfig to use # as an alias, like the following:

// tsconfig.json
{
    "baseUrl": "./",
    "paths": {
        "#/*": ["src/*"]
    }
}

// src/index.ts
{
    import { foo } from '#/foo'
    foo()
}

// src/foo.ts
{
    export const foo = () => console.log('foo')
}

Expected behavior

Aliased imports defined in tsconfig should work.

Change all instances of # with @ and pkgroll will run as expected.
