add support for deno

Troubleshooting

What happens and why is it incorrect

recently I've been trying to move my entire design-system build and test process to Deno.
what makes it hard is the different approach between nodejs typescript and deno typescript module path-finding methods.
deno wants us to import modules by file name extension like "../foo/bar.ts" but the node says we must import ts and js without the file extension. currently, I solve this by creating different workspaces for my front-end and builder codes that use Deno.

is there any way we can configure the bundler to ignore file extension so it would be acceptable by both rollup-typescript2 and Deno?
