Description

This PR adds a crate, package, and cli command similar to SVGR.

Motivation and Context

I thought it would be useful to have an alternative to SVGR (and @svgo/jsx) which is greatly popular but also not closely maintained.

The author himself mentions that future features should be built in Rust.

Additional thanks to Devon for passing on his implementation in Parcel for reference.

How Has This Been Tested?

• Extensive unit tests in oxvg_jsx and basic tests in @oxvg/jsx
• The oxvg jsx command is tested manually

Benchmarks

OXVG is at least 75x faster than SVGR in cli usage
