O(h)fetch data better!!

[Appstun]

I switched to ofetch for the TS/JS client, because Axios has had several security vulnerabilities in recently. Also, the package is smaller.
Read the updated README

The last Axios version can be found here (1.4.7 is the same client as 1.5.0). Keep in mind that the 1.4.7_axios branch does not get any updates anymore.
