add sd-streams from https://github.com/stardazed/sd-streams/blob/mast…

[nstott]

fixes #2828

@stardazed/streams was removed from third_party/ in https://github.com/denoland/deno/pull/2826/files

This adds sd streams from https://github.com/stardazed/sd-streams/tree/8928cf04b035fd02fb1340b7eb541c76be37e546 to cli/js/streams and reverts some of #2836

I've disabled some lints in cli/js/streams/ in order to get this to pass, I've marked them with TODOs,

As well, There are a few other TODO's that i've noted in streams/. notably, we're missing the DomException, and there are some gross type casts. as undefined as ..

There seems to be an impedance mismatch in the streams interface, eg, SDReadbleStream vs ReadableStream, but I'm not sure how much that matters at the moment

Should this be a git submodule rather than vendorize?

Should this be a git submodule rather than vendorize?

I was wondering this myself, but there are a bunch of changes that we need to make to the sd-source,
we need to bring in dom_types etc in various places (https://github.com/nstott/deno/blob/enable-sd-streams/cli/js/streams/pipe-to.ts#L17-L18), and we need to add the extension for all the imports (the source repo doesn't have those (https://github.com/stardazed/sd-streams/blob/master/packages/streams/src/pipe-to.ts#L8-L10).

Another option is to fork and float a patch, that way we could rebase over future updates...

These are called from cli/js/streams, and seem to be expected to exist in the dom.

I pulled most of these interfaces from https://github.com/microsoft/TypeScript/blob/master/lib/lib.dom.d.ts, I'm not sure whether this is right, or the right place to put these

@nstott I'd like to land this but it's red .. can you look into it?

[nstott]

will do!

[nstott]

That's done it.
I didn't realize these kinds were shared in both worlds.
I'm not sure this is the right place to put these.
There are a couple of places that sd-streams calls a DomException

https://github.com/stardazed/sd-streams/blob/45aa9d1ab8679cfcc3ca2959f6eef2276197d1c6/packages/streams/src/pipe-to.ts#L38

https://github.com/stardazed/sd-streams/blob/83df410ab4a0d1d049ecd3dccfefc9b36698a701/packages/streams/src/shared-internals.ts#L171

As far as I could tell, we didn't have an equivalent error type, so I shoved these into the DenoError bucket and punted

[nstott]

This is a lot of code that's being imported. If this is too big, I could stage these imports into smaller pieces.

for example, I could rip out the writer and transformer stuff from this pr, as we don't use those features yet, and don't have tests in place yet for that specific functionality.

FYI - this PR adds 1mb to the release executable on mac:

LGTM - thank you !
