Support for esm.ts using `node --loader ts-node/esm`

I use ts for my gulpfile, but some of the plugins i use (gulp-imagemin specifically), are esm.
So having a way to use both would be useful, as otherwise when one tries to run gulp, they get something like this:
```
[18:15:57] Requiring external module ts-node/register
TypeError: Unknown file extension ".ts" for /home/monyarm/Documents/gulp-gameoptimizer/gulpfile.ts

at importModuleDynamicallyWrapper (node:internal/vm/module:437:15) {

}
```

Start by reproducing the reported failure with a TypeScript gulpfile, an ESM plugin such as gulp-imagemin, and `node --loader ts-node/esm`. Trace how rechoir prepares modules with different extensions; done means a TypeScript gulpfile can use ESM plugins without the shown unknown-file-extension error.
