Use a more modern and optimized version of `antlr4ts`

Hey, thanks for the great lib, it gave me great hope in a NestJS project where i attempt to use Ory permissions.
Still i noticed some issues at runtime and they are related to antlr4ts, notably this one.
Since this lib is not maintained i looked for alternatives and found antlr4g which acts like a drop in replacement… except that is built and published as an ES module.
So it would involve producing an ESM lib as well…

Hey, you are welcome :) Sorry for responding late.
Thanks for your work and PR. It is really cool that you found a drop-in replacement 👍
Unfortunately I already started replacing antlr with an custom parser, which is several times faster for this simple syntax. You can see the result in #22 . Apparently I didn't merge it 🙈.
Maybe I find some time in the near future to finish the work and merge the changes made there.

Thanks for the reply.
Yes I get why you are going that path.
I started to work on a Regexp to parse tuple with a bit more flexibility (allow namespace | namespace:object | namespace:object#relation only) and the performance tests are quite surprising.

the result gives Regex winner apparently ... ;)

method	elements	time
antlr	100 w/ subject	12.93383ms
antlr	100 w/ subjectSet	12.521252ms
regex	100 w/ subject	0.318202ms
regex	100 w/ subjectSet	0.121128ms

I was not yet able to correctly isolate parentheses in subject segment so it's still WIP.
