This commit adds unstable workspace support. This is extremely
bare-bones and
minimal first-pass at this.
With this change `deno.json` supports specifying `workspaces` key, that
accepts a list of subdirectories. Each workspace can have its own import
map. It's required to specify a `"name"` and `"version"` properties in the
configuration file for the workspace:
```jsonc
// deno.json
{
"workspaces": [
"a",
"b"
},
"imports": {
"express": "npm:express@5"
}
}
```
``` jsonc
// a/deno.json
{
"name": "a",
"version": "1.0.2",
"imports": {
"kleur": "npm:kleur"
}
}
```
```jsonc
// b/deno.json
{
"name": "b",
"version": "0.51.0",
"imports": {
"chalk": "npm:chalk"
}
}
```
`--unstable-workspaces` flag is required to use this feature:
```
$ deno run --unstable-workspaces mod.ts
```
