qs.parse omitting empty string keys

See original GitHub issue

Hi, it will be nice to have this part configurable:

https://github.com/ljharb/qs/blob/542a5c7ff88d7229efa2e22c7c8a7d69375f5e72/lib/parse.js#L150-L152

current output:

qs.parse("=1&=2") === {}
qs.parse(" =1& =2") === { " ": ["1","2"] }

expected output :

qs.parse("=1&=2", { allowEmptyKeys: true }) === { "": ["1","2"] }

If you are ok - I can open a PR

“USP supports it” is a good argument, although your use cases are not convincing - if the key’s not present yet, then the value isn’t either, and I’m not clear on why the key would really evaluate to an empty string.

The PR adding this would have to add it to both parse and stringify, so that there could be a round trip.

Additionally, what happens with =1&=2, in the arrayFormat repeat vs brackets? What about []=1&[]=2?
