Support for loading transformers written in ESM

[uhyo]

Hello, thank you for the great tool! 🙂

Recently Jest supports loading transformers written in ESM through the requireOrImportModule util.

It would be great if jest-chain-transform could support such loaders too.

Downside is that this would require createTransformer function to be an async function, which is supported only by Jest >= 29.4, 😢

Noted. will look into this and try to support ESM loader

0.0.6 supports the ESM transformer to be chained.

Jest ESM is still under experiment. Please refer to https://jestjs.io/docs/ecmascript-modules.
