Source installation fails on Macintosh with python 3.10

### Describe the bug

Hi,

Decord is a dev dependency not maintained since couple years.
It does not have an ARM package available rendering it uninstallable on non-intel based macs

Suggestion is to move to eva-decord (https://github.com/georgia-tech-db/eva-decord) which doesnt have this problem.

Happy to raise a PR

### Steps to reproduce the bug

Source installation as mentioned in contributinog.md

### Expected behavior

Installation without decord failing to be installed.

### Environment info

python=3.10, M3 Mac
