add multi-field scoping for slugs

[mikekosulin]

• Add option for multi-field scoping in slugs, expanding beyond single-field/relation scopes without altering existing functionality

Looks great! Let's simplify the code a bit with a uniform Array(...).each ...

[dblock]

Much better, but the implementation is still a little confusing. See below. Thanks for hanging in here with me!

I think version.rb is the last thing.

LMK if the nit makes sense, otherwise I can merge.

@johnnyshields any comments/issues?

[dblock]

LGTM! Thanks. I'll wait for @johnnyshields to chime in, will merge this week if we don't hear from him.

Hey @dblock, @johnnyshields any updates on merging? 😊

[johnnyshields]

Hmmm... shouldn't this still create only one compound index? For example:

slug :name, scope: %i[company_id department_id]

# Should create
index company_id: 1, department_id: 1, _slugs: 1

# NOT
index company_id: 1, _slugs: 1
index department_id: 1, _slugs: 1

[mikekosulin]

Sorry for the late response. You're right, it creates only a compound index in this case. I've fixed it here and forgot to remove the note.
