feat: add require.cache support

[edusperoni]

Still needs android implementation

Allows for:

// some-script.js
console.log('some script logged');
// main.js
console.log('start');
require('./some-script.js');
delete require.cache['./some-script.js'];
console.log('delete');
require('./some-script.js');
console.log('end');
// output
start
some script logged
delete
some script logged
end
