Make it easier to use Semaphore with Bandada

[vplasencia]

Description

The idea of this issue is to make it easier for devs to use Semaphore with Bandada.

Right now it's a bit difficult to understand how to generate a Semaphore proof using a Bandada group. The issue is that devs would need to fetch the members of the Bandada group, then create a Semaphore group with those members and then generate the proof using the Semaphore group.

That can be a bit confusing for devs since they will need to know that there are two different groups and how to use each of them.

Possible ideas

Here are some ideas:

• Create a function to make it easier to generate a Semaphore proof (to fetch the Bandada members, create the Semaphore group and generate the proof under the hood).

• Create like a Semaphore wrapper compatible with Bandada (not just the generate proof function, there could be others functions).

• Create a very well explained tutorial with a step by step on how to do it so that devs can read and follow the steps.

Feel free to post other ideas.
