chore(rln): update dependencies and refactor code for compatibility (#291)

Browse Source

While publishing the release on crate io it turned out that we can't use
libraries without a version as it was for arc-circom.

During the upgrade to the new version it was also discovered that it is
possible to speed up input preparation for witness calculator by 4 times
by switching from bigint to Fr:

it was also checked that it is also possible to use iden3 as a
sub-module instead of copying code, but benchmarks showed that the new
iden3 version with u256 calculations and subsequent conversion of the
result to Fr is slower than the current implementation:

----

- Updated dependencies to their latest versions, including ark-ff,
ark-bn254, ark-std, and others to 0.5.0.
- Refactored circuit and iden3calc modules to use Fr instead of BigInt
for better type consistency.
- Improved utility functions for type conversions between Fr and U256.
- Adjusted Cargo.toml files for rln and utils to reflect new dependency
versions and features.
- Enhanced documentation and comments for clarity on changes made.

This update ensures compatibility with the latest versions of the Ark
framework and improves overall code quality.
