Remote Goatfile Imports

[zekroTJA]

Allow importing Goatfiles via the use statement from remote locations (inspired by deno's remote imports). This would allow centralizing Goatfiles on internal or external web servers.

Example:

use https://gist.githubusercontent.com/zekroTJA/somegistid/raw/somefileid/login.goat

It should also be possible to fingerprint remote imports with a hash. Example:

use https://gist.githubusercontent.com/zekroTJA/somegistid/raw/somefileid/login.goat@md5:5eb63bbbe01eeed093cb22bb8f5acdc3

This feature also opens some dicussion questions like how should relative imports in remote Goatfiles be handled?

Example:

https://gist.githubusercontent.com/zekroTJA/somegistid/raw/somefileid/index.goat

use ./login.goat

I think, in this case, the use ./login.goat should resolve to https://gist.githubusercontent.com/zekroTJA/somegistid/raw/somefileid/login.goat.

When a fingerprinted remote Goatfile is specified, imports inside these should be disallowed or must also be fingerprinted.
