Rewrite Nearley in TypeScript

[gajus]

I am open to contribute. @kach Would you accept a rewrite in TypeScript?

[0x6563]

@gajus I managed to get a bare minimum port to typescript https://github.com/0x6563/nearley-ts

I added a couple scripts "build"... naturally and "cli" which uses ts-node to test the cli.. npm run cli -- .\builtin\cow.ne

But I am looking at doing some aggressive rewriting that may or may not follow the design of this project.

As an update I've created a new repo where I've extensive refactoring and have been able to get profiling, benchmarks and tests working https://github.com/0x6563/grammar-well

@kach Could we deprecate Nearley in favor of grammar-well?

or add @0x6563 to nearley as a maintainer, so the project could continue living.
