Feature: alternate subcat support

[sreyassabbani]

See #8

This should work now, for both tossups & bonuses on both Sync and Async clients.

Example:

c = Sync()

print(c.random_tossup(alternate_subcategories=["Poetry"])[0])

This will send a GET request to the QB Reader API endpoint, automatically adding subcategories=Other%20Literature on to the querystring.

And for the async example:

a = Async()

async def t():
    a = await Async.create()

    print(
        (await a.random_tossup(alternate_subcategories=["Math"]))[0]
    )

    print(
        (await a.random_bonus(alternate_subcategories=["Computer Science"]))[0]
    )
    
    await a.close()

print(asyncio.run(t()))

I did see some oopsies after PR-ing. I believe we're going to have to squash those commits before merging.

I added some commits, the gist is that:

• You were correct initially that you should use .get for alternate_subcategory since not all questions have it
• For literature, the alternate subcategory corresponds to the Literature category, not the Other Literature subcategory. This is confusing because in this context, alternate_subcategory is a true alternate subcategory, but in all other contexts, it should be called "subsubcategory". This is a low priority issue but will likely be fixed in the future.
