tgz support

[stainless-em]

adds support for .tar.gz files from arbitrary urls

Would be very helpful for supporting Stainless packages in Val Town 👍

[stainless-em]

specifically preview versions, which we upload as tarballs to our own servers

I've found that val town doesn't acquire types for any val town sdk's actually via esm.sh but yes for npm, but I'm not sure why. (To be fair our type acquisition is super janky, so it might not be worth designing around too much.)

@stainless-em thanks, this is great! do you think we can remove the package name in the tgz path? like:

- https://esm.sh/tgz/preact@https%3A%2F%2Fregistry.yarnpkg.com%2Fpreact%2F-%2Fpreact-10.26.6.tgz
+ https://esm.sh/tgz/https%3A%2F%2Fregistry.yarnpkg.com%2Fpreact%2F-%2Fpreact-10.26.6.tgz

@stevekrouse i will look into it, can you please provide a code smaple for testing? Thanks🙏

Possibly, I tried that first actually. But then the PkgName in the EsmPath would need to be empty I think? Because there's no way to know what it is until the tarball is downloaded? idk

makes sense, can you please check the CI? i'm love to the merge this after the CI passing. Thanks!

tbc i think having the pkgname in the url is bad but i'm not familiar enough with how esm.sh is structured to know how to get rid of it 😅
