fixes #24

hi @CahidArda , why don't you use nanoid directly instead of using the self-defined function?

[hckhanh]

For the crypto.getRandomValues
I see it's currently supported natively by cloudflare now.

yes it was recently added to cloudflare, but we want to support older versions too.

when we use crypto directly, it doesn't work in Node 18. It gets crypto is not defined error.

Using nanoid had a similar issue if I remember correctly.

@CahidArda For the recent updates, I can use nanoid now without adding anything about node compatibility api.
So I think that you can use nanoid directly.

I will check again, thanks! @hckhanh

We released 0.1.5 with this update, we can change back to nanoid if it works well for us.
