Add a function to update many members at once to the LeanIMT implementation

[cedoor]

Is your feature request related to a problem? Please describe.

The idea is to create a function called updateMany. This function can be useful to update many members at once. It should be more efficient to update N members using updateMany once than using the update function N times.

Describe the solution you'd like

It would be nice to have an implementation for TypeScript and Solidity similar to the insertMany function (links below). Something to remember is that the TypeScript implementation will be different from the Solidity implementation, as the data saved and optimizations in both environments are different.

Additional context

• insertMany TypeScript implementation: https://github.com/privacy-scaling-explorations/zk-kit/blob/main/packages/lean-imt/src/lean-imt.ts#L162
• insertMany Solidity implementation: https://github.com/privacy-scaling-explorations/zk-kit.solidity/blob/main/packages/lean-imt/contracts/InternalLeanIMT.sol#L91

@cedoor Should we mark this as completed? See #104

This is another task. That's the insertMany function. This would be the updateMany.
