Loosen the version constraint of Faker to avoid dependency conflicts

[NeolithEra]

Hi, certstream locked the version constraint of Faker as Faker==0.9.1, which leads to a troubling scenario that its direct downstream project [doccano, orcamentos] has to lock Faker.

Could you please loosen the version constraint of Faker?
Benefit of this is that users using both of [doccano, orcamentos] and Faker can upgrade their third party libraries in a timely manner to reduce technical debts.

Solution

The dependency trees of your project and affected downstream projects are shown as follows.
Taking the version constraints of upstream and downstream projects into comprehensive consideration, you can

1. Loosen Faker==0.9.1 to be Faker>=0.9.1.
2. Loosen Faker==0.9.1 to be Faker==*.
3. Try to add an upper bound for Faker’ version constraint, according to your compatibility.

@klen Please let me know your choice. I can submit a PR to fix this issue.

Thanks for your attention.
Best,
Neolith
