Buffrs does not allow underscores in the package.name field and recommends hyphens as a word separator. On the other hand, the Protobuf package ...; directive does not accept hyphens and underscores can be used as a word separator.

This leads to inconsistencies between the package and import directive.

# Proto.toml
[package]
name = "foo-bar"
type = "api"
version = "0.1.0"

// proto/service.proto
package foo_bar;
import "foo-bar/messages.proto";

This is because Buffrs will construct the proto/vendor folder as

proto/vendor/
  foo-bar/
    service.proto
    messages.proto

I would argue that this is inconsistent and confusing for no benefit and that Buffrs should instead align with the Protobuf specification; if not for the Buffrs package.name, at least for the generated directory structure.
